Anyone know the NLS (National Language Service) code the en_GB (British English)

As in the code used in the /L: command line option of setup.exe.

Extremely irritatingly this article has English US and lots of others but not english UK.

I need the number code not the character code (en_GB)
Is it a constant, or is it specific to an application?

On second thoughts, I think I found what I’m looking for…

Don’t forget that there are many ‘setup.exe’ programs and they may not support the LCID you want.
