When I enter a name at attendee invitation, the autocomplete works correctly until I enter an UTF8 character. The characters what exists in another character table (latin 1 in my case) doesn't encoded correctly when passing to LDAP.
The same lookups in the addressbook, or in mail composition it works correctly.
It sends the LDAP search query by representing the character with %u0151 form instead of the form \C3\B6. |
