This is what it looks like, yes. But looking at your other problems with
charset conversions, the problem might be anywhere else, though I have no
idea where.

A simple fix for this single case would be to pass the full name that you
retrieved from ldap and that seems to be iso-8859-1 through
String::convertCharset() inside your hook.
