My software depends on the Indic script : 'Regional a开发者_StackOverflownd Language Options' in control panel (Unicode support) to be installed on windows pc

Using C# How do I check if the unicode is installed on the pc?

You can use IsValidLocale with the locale ID that you want.

And you can build the locale using MAKELCID and the language codes in WinNT.h (for instance 0x439 is Hindi, MAKELCID(LANG_HINDI,SUBLANG_DEFAULT))
