Sorry,

My meaning is can I use pango/gtk2 under GB18030 locale? and how can I let a gtk2 program use my XIM server?

I had tried gtk-demo shipped with gtk+-1.3.9, but I cannot call out my XIM input server. And I cannot copy/paste string from other program.

How can I test whether pango/gtk+ supports GB18030 locale?

Is there any demo program which will edit or show text file encoded in GB18030?

Many thanks

James Su

Does anybody can give me some suggestion?

btw, GB18030 is a variable length encoding, which can be 1, 2 or 4 bytes
for one code point.

What do you mean by 'support'?

All strings used in GTK 1.3.x must be converted to Unicode; there is
no way to use locale strings.

Support for converting to/from a particular encoding
(g_locale_to_utf8(), g_convert(), etc.) is provided by your iconv()
implementation in the standard C library.

For GTK 1.2.x, all strings must be in the locale's encoding, which
means you would add support for an encoding on the standard C library
and Xlib level.
