[support] customizing language switcher in D7

[Bert Van Kets]

Hi all,

I am building a multi language site in Drupal 7 and use the regular 
language switching block. Positioning the block and language links is 
not a problem.
I can't find how to add a character between the different languages in 
D7. I have found D6 samples. but none that work in D7. :-(

How can I add a | character between the language switching links?

Thanks.

Bert

P.S. I am using a Zen based subtheme
