[ubuntu-in] Locale en_IN or en_IN.UTF-8 ??

[Jasbir Khehra]

Hi,
Choosing language as  English(India) during the install process makes
en_IN the default locale of the system.But this causes the gtk1 using
applications not to show their menu eg. audaciity,xmms (
https://bugs.launchpad.net/ubuntu/+source/audacity/+bug/65549 ) .
Changing the locale to en_US solves this problem somehow. Also noticed
there was no .UTF-8 for en_IN when listing the locales using locale -a
. So generating the en_IN.UTF-8 locale and making it the default,
solves the gtk1 bug plus other irritants.
So my questions are,
a) what is the difference between en_IN and en_IN.UTF-8?
b) why cant en_IN.UTF-8 be the default locale when selecting English
(India) as the preferred language?

I have noticed this behaviour in Ubuntu 7.04 and 7.10 , and no other
language packs have been installed.
Can some one check this out in 8.04?
