Titelling image array in montage -- German umlauts

Hi,

I am trying to generate index prints of all photographs contained in certain directories (contaning the word "digibis") in a Windows directory tree. This is done by the help of two DOS batch files:

SET COUNT=0
FOR /F %%a in ('DIR /S /B /AD ^| Find "digibis"') DO Call c.bat "%%a"

An "c.bat" being:

SET /A COUNT+=1
ECHO %~1 >title.txt
montage  -geometry 210x140+0+5 -tile 6x -font courier -pointsize 8 -title @title.txt %1\*.jpg -quality 30%% %count%.jpg


The problem occurs in the last line of "c.bat", where German umlauts are interchanged by crude characters. Is there any means by which I can instruct montage to use a certain coding for the text supplied in "title.txt"?

........................

I will now shortly explain what's happening in the batch files, although this is not neccessary to understand my problem:

The two batch files are placed in the root directory of the tree and are called from there.

The FOR loop in the first batch file runs through the directory tree, filters all directory names containing the string "digibis" and passes each of these directories to C.BAT as the single command line parameter. 

C.BAT increases the environment variable COUNT, echoes the directory name into TITLE.TXT (which is necessary because of the backslash used in Windows pathnames, which would otherwise be considered as starting an escape sequence). 

MONTAGE then generates an index print of all images in the subdirectory and stores it in the file N.JPG in the root directory, with N being an integer number.

Please note that the operation performed in C.BAT cannot be performed within the FOR loop, even not if bracketed by parantheses "(", ")": The environment variable COUNT would not be increased while running the FOR loop (for reasons that I could not figure out...).
