[Zope] can not use -L in zope startup

[Robert Rottermann]

Hi,
I would like to use Unicode support in Zope (to use non ASCII characters in
structured text)
However when I try to start zope with the -l command line switch I get an
error.

The specified locale is not supported by your system.
See your operating system documentation for more
information on locale support.

I tried to set the environment variable LC_ALL to different values. Always
to the same effect.

This is on both win2000 and Linux.

What can I do ?

thanks
Robert
