[Scilab-Dev] Localization for Windows Multilanguage

[Yung-Jang Lee]

Allan,

As I say, output of 'gettext'  becomes un-predicable ,  some of output
messages are converted to unrecognized strings.

To see this, under my Chinese-Traditional (Zh-TW) Windows, with

http://www.scilab.org/download/dailyDownload.php?filename=scilab-master-1233250238.exe&date=2009-01-30

installed. After

   setdefaultlanguage(' ru_RU')

, for  Russian version , message '&File'  became unrecognized strings.

and with

  setdefaultlanguage(' zh_CN')

, for Chinese-Simpilfied version, message '&Resume'  became
unrecognized strings.

And I believe that most of the messages that can display on the Java
Console with  "scilab-master-1233250238.exe"  is due to a sole reason
that that they  fail to converted in function localeToUTF, you can
check this with a debug breakpoint.

So we need a gettext library with  "bind_textdomain_codeset" provided
and also a "putenv" wrap function ("gettext_putenv") to resolve this
bug.

I did this patch just because you said this is VERY important  for
Vista and XP's  Multilanguage enviroments.

For most users, this bug is NOT SO important  for them.

Regards,

Yung-Jang Lee
