htdig with utf8

Hi,
I'm running a Debian Server with following locales

LANG=3Dde_DE.UTF-8
LANGUAGE=3Dde_DE:en_US:de_LU:de_CH:de_BE:de_AT
LC_CTYPE=3D"de_DE.UTF-8"
LC_NUMERIC=3D"de_DE.UTF-8"
LC_TIME=3D"de_DE.UTF-8"
LC_COLLATE=3D"de_DE.UTF-8"
LC_MONETARY=3D"de_DE.UTF-8"
LC_MESSAGES=3D"de_DE.UTF-8"
LC_PAPER=3D"de_DE.UTF-8"
LC_NAME=3D"de_DE.UTF-8"
LC_ADDRESS=3D"de_DE.UTF-8"
LC_TELEPHONE=3D"de_DE.UTF-8"
LC_MEASUREMENT=3D"de_DE.UTF-8"
LC_IDENTIFICATION=3D"de_DE.UTF-8"
LC_ALL=3D

and

ht://Dig 3.2.0b6

My htdig.conf begins with

locale: de_DE
locale: de_DE.UTF-8

htdig runs fine and finds all words without german 'Umlaute' (=E4=FC=F6...).
But if I try to find any word with a german 'Umlaut' I get no result!

Isn't htdig supporting utf8??

Best regards
Bernd Heim
