Languages in Windows Installer

Hi,

In the Windows Installer of the trunk and 2.8.6 as well, the Language
Selection Dialog (for the Windows Installer only) shows only about 20
Languages. However we have the Lang NSH files for about 50 Languages
in msvc2008/Setup/NSISv2/lang.

The reason for this is a feature introduced in NSIS :
http://nsis.sourceforge.net/Why_does_the_language_selection_dialog_hide_some_languages

It says that language selection dialog of Modern UI hides languages
unsupported by the user's selected codepage by default. However if we
want to display all the languages we can do so by simply defining
MUI_LANGDLL_ALLLANGUAGES.

But the question is should we display all languages irrespective of
the user's codepage ? or keep it as it is ?

Thanks,
Prashant
