Thank you Jirka for your explanation, that was very helpful. I never realized the bottom bar of Oxygen XML Author telling me the Unicode code for the current character.

When you say "I'm putting here directly encoded non-breaking space" which code sequence are you using instead of   ?

Btw I made an interesting experience. My framework now writes a   into my XML file. When I switch from Author to Text mode, this   is not written in the text, it just looks like a "regular" space. But the bottom bar says it is a U+00A0. So everything is fine except the visual representation in the text.

When I close the XML file and open it again in text mode, there is suddenly a   displayed. So everything is even better after reopening the file.

Thanks and kind regards
Christian

Are you sure? At the bottom bar you can see Unicode code for character
under the caret. Normal space is U+0020 and non-breaking U+00A0.

What do I have to put between my opening and closing <String> tags?

I'm putting here directly encoded non-breaking space, but   should
work same.
