A patch in which the patch name contains a funny sequence of
characters, originally meant to be a 'ü', gets displayed colorized, which I 
think, should not be.

This is the relevant part of the outout:

aragon: .../PITZ-Controls/tailor > darcs 
changes --repo=tailor_d1 --xml-output --patches='rkmann' | grep name                
        <name>Versions 42 (Modulator) and 10 (Gun) as sent by K.B\fcrkmann 
to Jakob Rytter on 06-06-06</name>

and this is what it looks like byte by byte, look for 'esc':

This happens with both darcs-1.09 and darcs-2.00.

A stop-gap work-around is to

  export DARCS_DONT_COLOR=1
