As the function was introduced for the edge-case of Turkish (it has
lower and upper case i's with and without dot) I don't think it it's
necessary to burden the function with character set handling.

I have used the if-construct myself but I loath it. Both BE and FE
should use the same character set and label mechanism. The context
guessing is horrible.

I suggest to postpone this patch to 4.4 and come up with a refactored
charcter set handling. I propose to drop $LANG and use a character set
and a label singleton instead in the BE. The FE should use the same classes.
