[Zope] can not use umlaute with structered text

[Robert Rottermann]

Hi there,

I found out that as soon a text contains umlauts the codes to change its
formatting like **xxx** do not work anymore.

I was digging in the source and found  locale.setlocale. However this
function does not work. Calling it creates a traceback saying that the local
can not be changed.

How can this function be used.
Or is there an other way to be able to use umlauts?

thanks

Robert
