Hi Silvan,
since I've also to handle "dschörmän" Umlauts, I've put a converstion in
the following procedure:
*import cgiimport sys#
-------------------------------------------------------------------------#
convert_special_chars(label)## Converts string to be compatible to UTF-8#
and to HTML (e.g. ä to ä)## parameter: label as string#
-------------------------------------------------------------------------def
convert_special_chars(label): if sys.version_info[0] == 2: # is Python
2.x label = label.decode('utf-8') label = cgi.escape(label)
label = label.encode('ascii', 'xmlcharrefreplace') return label*
Have a try, hope it helps!
Best regards
Clemens
