It is nice, that also someone else sees it this way.

But @ Peter: I will add a kind of disclaimer below my posts:
I have searched Google and other available search-engines without result.
This is my reason I post here.
Please only write your answer, if you
a. have one and
b. want to descend to answering me.

I put the line you posted in a extTables.php and it works!
I can now enter be-usernames with capital-letters.

Steffen, can you tell me, why this is not possible by default?
Meaning: Is there now the danger that something won't work anymore?

Kind regards
