guiserver not work UTF8 encoding

Postby unya » Fri Aug 06, 2010 10:30 am

Hello,

Java(guiserver.jar) need start option "-Dfile.encoding=UTF8".

I tried add setProperty() in guiserver(main), but NOT WORK.(Java BUG?)

Code: Select all
System.setProperty("file.encoding", "UTF8") and "UTF-8"


Added java start option. the changed work font-name demo.

Code: Select all
---- guiserver.lsp changed ----
(define (init (portIn 47011) (host "127.0.0.1") manual)
        ; check for server portIn and if this was started by java
        (if (main-args 2) (set 'portIn (int (main-args 2) portIn)))
        ; if guiserver.jar did not start this process then guiserver.jar
        ; still has to be started, except when manual parameter is true
        (if (and (not (= (main-args 3) "javastart")) (not manual))
                (if (= ostype "Win32")
                        ;(process (string "cmd /c " server-path " " portIn))
                        (process (string "javaw.exe -Dfile.encoding=UTF8 -jar " server-path " " portIn))

                        (= ostype "OSX")
                        ;(process (string "/usr/bin/java -jar " server-path " " portIn))
                        (process (string "/usr/bin/java -Dfile.encoding=UTF8 -jar " server-path " " portIn))

                        (env "JAVA_HOME")
                        ;(process (string (env "JAVA_HOME") "/bin/java -jar " server-path " " portIn))
                        (process (string (env "JAVA_HOME") "/bin/java -Dfile.encoding=UTF8 -jar " server-path " " portIn))

                        ;(process (string "/usr/bin/java -jar " server-path " " portIn))
                        (process (string "/usr/bin/java -Dfile.encoding=UTF8 -jar " server-path " " portIn))

                )
        )
   ....

newLISP-GS switches character sets during runt-time not Java start-up! So when you specify '-Dfile.encoding=UTF8' during Java start up, it will get overwritten by 'init' in guiserver.lsp to whatever flavor of newLISP is running. In many of the Java files you find the following lines:

Code: Select all
if(guiserver.UTF8)
            try {
            text = new String(text.getBytes(), "UTF-8");
            } catch (UnsupportedEncodingException ee) {}

The 'guiserver.UTF8' variable is set during the 'init' function of guiserver.lsp looking for the built in 'utf8' primitive function in the newLISP process. If 'utf8' is not 'nil' then 'guiserver.UTF8' is set to 'true'. The following snippet from guiserver.lsp occures in the definition of 'init':

Code: Select all
(define (init (portIn 47011) (host "127.0.0.1") manual)

(gs:set-utf8 (primitive? MAIN:utf8))
)

The function 'gs:set-utf8' sets the 'guiserver.UTF8' variable in Java. So guiserver.lsp does the switching during run-time automatically depending on newLISP version running. As an alternative, one could use System.setProperty() during run time.

The best would be, to ship only the newLISP UTF8 version for MS Windows, as done on Mac OS X, but many European countries use special flavors of the 8-byte ISO 8859 character set. As many people use editor and text files encoded using these character sets, they wouldn't be able to work with the UTF8 version of newLISP. Countries using multibyte UNICODE character sets in Windows (mostly in Asia), can download the UTF8 versions in http://www.newlisp.org/downloads/UTF-8_win32/ .

Japanese Windows environment, Java is a good deal to UTF8, "-Dfile.encoding = UTF8" option is also necessary to say Q & A can be seen.

Is other Japanese text in the editor and output fine? With Russian UTF8 I cannot repeat the problem in either WinXP, Linux or Mac OS X, but have no font names with utf8 to test.

I wonder if this problem is only in gs:get-fonts. Does the following fix for getFonts() in guiserver.java solve the problem ?

Code: Select all
public void getFonts(StringTokenizer tokens)
    {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    String[] fontNames = ge.getAvailableFontFamilyNames();
    String item;

    guiserver.out.print("(set 'gs:fonts '( ");
    for(int i = 0; i < fontNames.length; i++)
        {
        item = fontNames[i];
        if(guiserver.UTF8)
            try { item = new String(item.getBytes("UTF-8"));
            } catch (UnsupportedEncodingException exc) { }
        guiserver.out.print("\"" + Base64Coder.encodeString(item) + "\" ");
        }
    guiserver.out.println(")) ");
    guiserver.out.flush();
    }

I tried only Label/ListBox widget.
I'll check...

I tried your patch.
fontname can see(or read) on Windows Terminal, but it should not be see(or read) UTF8 fontname.
the guiserver returns MS932 fontname when java started without option.

P.S.
I've tried "System.setProperty("file.encoding", "UTF8")", NO EFFECT encoding this Java version.
In Java 1.6, "-Dfile.encoding" seems valid.
The Java(CJK) version of the "file.encoding" seems to have different behavior and treatment options.

The MS932 Stream Socket can read the font names remain, guiserver is working fine.
The String Class Other Widget to work I think that if you change the generation.

To see all of the Widget, please some time.

This works only for getting/displaying the fonts (retrieving Java-internal strings)

Code: Select all
new String(text.getBytes("UTF-8"), "UTF-8")

in all other situations either
Code: Select all
new String(text.getBytes(), "UTF-8") ; for setText()

or
Code: Select all
new String(text.getBytes("UTF-8")) ; for getText()

should be used.

A new newlisp-10.2.12.tgz can be found here:

http://www.newlisp.org/downloads/develo ... nprogress/

it contains the fix for 'gs:get-fonts' when font names contain UTF-8 characters, but it doesn't contain any other changes, as those will break UTF-8 behavior, at least in my tests on Mac OS X and Win32 XP and using widget-demo-ru.lsp and of course a UTF-8 version of newlisp.exe.

newlisp-x.x.x/guisserver/widget-demo-ru.lsp is a widget test program for the Russian UTF-8 characters. I wonder if you could make a widget-demo-jp.lsp for the Japanese language, which could be useful for testing and could be included in the distribution?

Also, I made the following strange observation on MS Windows. Starting on the command line with: "java -Dfile.encoding=UTF8 -jar guiserver.jar …" is equivalent to starting newLISP-GS clicking the installed desktop icon.

Certain UTF-8 features would not work doing: "java -jar guiserver.jar …" without the "-Dfile.encoding=UTF=8", but they would work when starting with the desktop icon. If you look into the link-icon properties of the desktop icon you see the application started like: "guiserver.jar 47011 newlisp-edit.lsp", as if ".jar" is registered to be started with java.exe or javaw.exe. It looks similar to the commandline but has a different effect.

Created for the Japanese version of the test "widget-demo-jp.lsp" Attach.

In addition, to add the image.
Russian and Japanese versions of the image,-Dfile.encoding = UTF8 is the result of running put.

Runs fine on Mac OS X 10.6 and UBUNTU Linux 10.4 under newLISP 10.2.8 and 10.2.12 and with all of the following mehods and without the gs:set-utf8 statement in widgets-demo-jp.lsp :

- newlisp widgets-demo-jp.lsp
- java -jar /usr/share/newlisp/guiserver.jar 47011 widgets-demo-jp.lsp
- start newLISP-GS from desktop icon, then load widgets-demo-jp.lsp

On Windows, I don't have the Japanese font installed, but the Russian version runs.

I wonder what is is with with either the MS932 font setting or some other specialty of your Windows installation, that it only works with java -Dfile.encoding=UTF8 on your system?

Perhaps other Japanese users (e.g. Johu ?) can help us with their experience?

In any case, many thanks for your help Unya.

Thanks for this work, unya and Lutz.
At last, I could know how to run newLISP-GS in UTF8 mode.

I wonder what is is with with either the MS932 font setting or some other specialty of your Windows installation, that it only works with java -Dfile.encoding=UTF8 on your system?


If it means that the widgets-demo-jp.lsp runs in both Shift-JIS code(MS932) and UTF8 code, it is the following link :

http://cid-23a9a25e1aec3626.office.live.com/self.aspx/.Public/widgets-demo-jp.zip

maybe.

P.S.
Sorry, I have up-loaded a wrong file.
Now, I corrected it.

Re: guiserver not work UTF8 encoding

Postby unya » Wed Aug 11, 2010 4:12 pm

Thank you, Lutz and johu,
I have more idea.

Encoding system environment because Java is running on the mind may be led to convert the character stream.
I was investigated, NewLisp is UTF8, Java is a mismatch in the MS932 is happening.
(Java returns fontname is "MS932" via base64-enc)
So even though Java to work,-Dfile.encoding = UTF8 I might be required.

And as follows, allfonts-demo.lsp was working without -Dfile.encoding=UTF8.

I do not know which method is better/best.

Replace encodeString() and decodeString()

I'think String.getBytes() depends System.Locale.Environment. (after added comment)

Code: Select all
// Base64Coder.java

import java.io.UnsupportedEncodingException ;

...

//public static String encodeString (String s) {
//   return new String(encode(s.getBytes())); }
    public static String encodeString (String s) {
   byte [] bs ;
   try {
       bs = s.getBytes("UTF-8") ;
       String r = new String(encode(bs)) ;
//       System.out.println(r) ;
       return r ;
   } catch (UnsupportedEncodingException ee) {}
   return new String("") ;
    }

...

//public static String decodeString (String s) {
//   if(s.equals("nil")) return("");
//   return new String(decode(s)); }
    public static String decodeString(String s) {
   System.out.println("decode in : " + s) ;
   if(s.equals("nil")) return("");
   try {
       String r = new String(decode(s), "UTF-8") ;
//       System.out.println("decode : " + r) ;
       return r ;
   } catch (UnsupportedEncodingException ee) {}
   return ("") ;
    }
...



Text Encoding unconscious, Stream(socket) through base64_UTF8 text.
Code: Select all
// guiserver.java

public void getFonts(StringTokenizer tokens)
{
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    String[] fontNames = ge.getAvailableFontFamilyNames();
    String item;

    guiserver.out.print("(set 'gs:fonts '( ");
    for(int i = 0; i < fontNames.length; i++)
        {
        item = fontNames[i];
        guiserver.out.print("\"" + Base64Coder.encodeString(item) + "\" ");
        }
    guiserver.out.println(")) ");
    guiserver.out.flush();
    }




Text Encoding unconscious, Stream(socket) through base64_UTF8 text.
Code: Select all
// LabelWidget.java
...
public void setText(StringTokenizer tokens)
   {
       String base64text = tokens.nextToken() ;
//       System.out.println("Label setText : " + base64text) ;
       String text = Base64Coder.decodeString(base64text) ;
   label.setText(text);
   }
...


Thank you for using your precious time.

Thanks Unya and Johu.

I have changed Base64Coder.java to include Unya's a encodeStringUTF8(String) and decodeStringUTF8(String) and all Widgets now use these and avoid String.getBytes():

http://www.newlisp.org/downloads/develo ... nprogress/

I hope in newlisp-10.2.13.tgz character encoding MS932 now works without -Dfile.encoding=UTF8

ps: updated newlisp-10.2.13.tgz, a few things were still missing

Thank you Lutz and Johu.

newlisp-10.2.13.tgz is working without -Dfile.encoding=UTF8.

I tried test delete "if (guiserver.UTF8) { ... }" from all Java source(base 10.2.12).

It's working without "-Dfile.encoding=UTF8".
Users can selectable Java running environment ,UTF8(with "-Dfile.encoding=UTF8") or System.Locale(without option).

java/*.java
guiserver.jar

added Dump.java for debug HexDump.

… which method is better/best.

Both work well now, but using "if (guiserver.UTF8)" we can switch UTF-8 mode on/off from newLISP. This way we can start guiserver.jar first, as required when starting with the desktop icon on Windows or on Mac OS X. When loading "guiserver.lsp", newLISP then automatically switches to UTF-8 in 'gs:init', if required.

For your information,

I wrote widgets-demo-jp.lsp without hexadecimal code, and added :

Code: Select all
(if utf8 (load "UTF8-title.lsp") (load "SJIS-title.lsp"))

UTF8-title.lsp contains UTF-8 characters.
SJIS-title.lsp contains Shift-JIS characters.
