newLISP v.10.4.5 on Win32 IPv4/6 UTF-8 libffi, execute 'newlisp -h' for more info.
(define (url-encode str)
(replace {([^a-zA-Z0-9])} str (format "%%%2X" (char $1)) 0))
(url-encode "倒")
ERR: invalid UTF8 string in function char。
need help.

You have to set the UTF-8 option for regular expressions:
Code: Select all
(define (url-encode str)
(replace {([^a-zA-Z0-9])} str (format "%%%2X" (char $1)) 2048))
> (url-encode "爱")
"%7231"
> $1
"爱"
> (char 0x7231)
"爱"
See here for all options:

much thanks to Lutz.
but in url:
(url-encode "爱")
should be %e7%88%b1
how to do that?

Code: Select all
(define (url-encode str)
(join (map (fn (chr) (format "%%%02x" chr)) (unpack (dup "b" (length str)) str))))
(url-encode "所有的愛是公平的")
;=> "%e6%89%80%e6%9c%89%e7%9a%84%e6%84%9b%e6%98%af%e5%85%ac%e5%b9%b3%e7%9a%84"
Ps: this and a url-decode for utf-8, you can now also find here:

Thank you Lutz.
It works.
I should keep on learning NEWLISP.
ps: found in google :
https://github.com/kosh04/newlisp.snipp ... er/net.lsp
;; URL translation of hex codes with dynamic replacement
(define (url-encode url (literal ""))
(join (map (lambda (c)
(if (or (regex "[-A-Za-z0-9$_.+!*'(|),]" (char c))
(member (char c) literal))
(char c)
(format "%%%02X" c)))
;; 8-bit clean
(unpack (dup "b" (length url)) url))))
haven't test it.
