The "backtick" character has a special meaning with MySQL. Please see here:
http://dev.mysql.com/doc/refman/5.0/en/identifiers.html
A general rule to stay out of trouble is not use anything else than a subset of latin1 characters for your identifiers (a-z0-9_) in the first place and avoid reserved words
http://dev.mysql.com/doc/refman/5.0/en/reserved-words.html
If you stick to that you are fine. And as the internal identifiers do not need to be exposed to the end users anyway there should not be any complains from that side as well.
In Workbench you can then use all its documentation features to add documentation to your schema objects in your native language since we store everything in UTF8.
Sure, some people insist on using umlauts (ä, ü, ö) or spaces or special characters like ' or # in their identifiers. But then they should not complain in the first place.
