hi all,

in an html textarea, i input some chinese text, and receive the text from
the http request body. i tried to use uri-decode to restore the text, but
failed:
(display (uri-decode "%E5%B0%8F"))

any suggestions?

thanks a lot for your helps.

It's OK in my system.
--------------cut---------------
scheme@(guile-user)> (display (uri-decode "%E5%B0%8F"))
小scheme@(guile-user)> 
--------------end---------------

Can you show the error message?

It may be that Guile is decoding it correctly, but your terminal program is
unable to display the characters. At least, I often see '?' in place of
characters that my terminal can't display.

I'm not sure how to test this right now, though.

It sounds like your locale has not been set.  The locale is set
automatically during an interactive Guile session, but within a script
you must manually set it using (setlocale LC_ALL "").
