pgAdmin3 - Language support on Solaris

Hi All,

I came to know that pgAdmin3 fails to support all the languages on
Solaris platform.
However, it works when I choose ja_JP, zh_CN, and  zh_TW languages.
For the rest, I get an error the following error message:

An error occurred: Cannot set locale to 'fr_FR'

Did anyone notice this? Is it a problem with pgAdmin or Solaris?
I like to fix this issue. Any thoughts?

Thanks
Dhanaraj
