Thanks!!
Actually I came to try my code on another box today which still runs
python2.2 and found that my original code crashed because neither
sys.getpreferredencoding() nor sys.stdin.encoding exist and
locale.getdefaultlocale()[1] returnd 'de' .So I changed my
_sysencoding() function to this:
def _sysencoding():
# try to guess the system default encoding
try:
enc = locale.getpreferredencoding().lower()
if _find_codec(enc):
print 'Setting locale to %s' % enc
return enc
except AttributeError:
# our python is too old, try something else
pass
locale.setlocale(locale.LC_ALL, "")
enc = locale.nl_langinfo(locale.CODESET).lower()
if _find_codec(enc):
print 'Setting locale to %s' % enc
return enc
# the last try
enc = locale.getdefaultlocale()[1].lower()
if _find_codec(enc):
print 'Setting locale to %s' % enc
return enc
# aargh, nothing good found, fall back to latin1 and hope for the
best
print 'Warning: cannot find usable locale, using latin-1'
return 'iso-8859-1'

I guess I should have done so from the beginning.
Thanks again and best regards
