One of the systems we currently use at work just shortens the first name to 1-4 characters and adds the last name. I still have to figure out on what criteria.

The bad thing about it is that it sometimes changes names to the other gender - think Erica to Eric. I never realized how often that could be done in my language by chance and it only affects female names.

Normally that would matter much but three weeks ago they established that account name as our new matrix chat handles...
