[imp] Search within Addressbook and Turba installed

[ES]

Hi,
I'm using Lotus Domino 5.06a as my mailserver, this supports LDAP.
I'm using IMP 3.2 and HORDE 2.2 from the stable release.

Now I'm going to send my mails and when using the addressbook in the 
compose-window, then I get the following strange behaviour with german 
umlauts:

Searching in the LDAP-Addressbook on my domino-server with a 
searchcriteria like Müller produces Frank Müller for example.

Searching in the LDAP-Addressbook on my domino-server with a blannk 
searchcriteria produces a list of all entries, but ALL of the german 
umlauts are somewhat escaped.

Anyone around who could explain and tell a workaround to get the umlauts 
shown correctly?
