[Discuss] How to change language in debian ?

[J.Bakshi]

Hi,

recently I have installed debian at my friend's PC. during installation I 
selected *British English* as language setting. Now the problem is I can't 
get the *pipe* symbol rather than I am getting *tilde* sign. not only that
some other symbol keys are also behaving differently. I think changing the 
language setting to *American English* may solve the problem. How can I do 
that ? please suggest.

thanks for your time.
