[Scilab-Dev] Localization for Windows Multilanguage

[Allan CORNET]

Hi,

Please notice that on current master, with Sylvestre and Antoine modifications 
http://bugzilla.scilab.org/show_bug.cgi?id=4005

http://gitweb.scilab.org/?p=scilab;a=commit;h=67660b64ac3914055233035fa1ee3c04eaa41ed4

I have no more this problem with menus grayed.
I checked with this version: http://www.scilab.org/download/dailyDownload.php?filename=scilab-master-1233250238.exe&date=2009-01-30

Current version used by scilab of libintl for Windows is 0.14.
This version was built with Visual studio 2008 for x86 and x64.

I will update libintl to 0.17 for scilab 5.2
(quickly on master)

Thanks you for your help

Best regards

Allan

Objet : [Scilab-Dev] Localization for Windows Multilanguage

Sylvestre  and all,

Allan reported a  localization bug for Windows  Multilanguage environment ( http://lists.scilab.org/cgi-bin/ezmlm-browse?list=dev&cmd=showmsg&msgnum=1169
).

This bug is not easy fixed with current Prequirements, for the GETTEXT library is too old and lack function I needed for a patch.

I just fixed this bug with a new  Prequirements library for  iconv.dll ,GNU_gettext.dll. Attached is the patch for Scilab as well as Prequirements libraries.

There is a ReadMe file in  'src' directory of the Prequirements patch, that describe how to create these libraries.


The reason to update the Prequirements  libraries is,

   The output string of  'gettext'  provided by current Prequirements
(GNU_gettext.dll) is fixed to system installed  encoding. If user change default language in Scilab or select other language form the "Regional and Language options" in control panel Windows,  the outputs
 of 'gettext'   are  unpredictable. Some of them are in unconverted
UTF8 format and some of them being  badly converted to unrecognized strings.

We need a 'gettext' version that always return  UTF8 string.
According to documentation of GNU gettext library, this can be provided with function  'bind_textdomain_codeset'. I just to set output encoding to "UTF-8" as

             bind_textdomain_codeset ('scilab',"UTF-8");

and "gettext"  , "dgettext"  will always return string in UTF-8 format. With this way, I don't need to wrap 'gettext' with 'localeToUTF'.

But GNU_gettext  in Prequirements  is too old to have function 'bind_textdomain_codeset' , I need to  update it,

I had test this patch with Chinese-Traditional(zh_TW) Windows Xp with
default language set to   "fr_FR","zh_CN" and "ru_RU". Scilab's
localization  function work well in this tests.
