Hello.
In my opinion, this is not really a bug (however, I might be wrong - I
don't speak danish :) O umlaut is an old writing of o with / through. See:
http://users.cybercity.dk/~nmb3879/tree.html
Probably latin1_danish_ci was designed to serve fields which contain
only Danish symbols. If you have a look at section latin1_danish_ci in:
/usr/share/mysql/characters/latin1.xml
you will see the same numbers in different places - that means that
different symbols are equal in this collation. If you want to properly
handle extended set of characters use latin1_general_ci, or you may want
to add your own collation. See:
http://dev.mysql.com/doc/mysql/en/adding-character-set.html
