Non-Breaking Spaces in Structured FM9 Make a File Invalid

Hi All,

I'm working with Structured FrameMaker to author XML and I'm facing a problem that I've never had with FM 7.2: if I have a non-breaking space in a variable definition, when FM saves the file, it replaces the non-breaking space with the character code 0x11. I get the error message that states the file contains invalid characters. Worst of all, I can't reopen this file any longer with FM...

Is there any solution or workaround? For me it's a crucial issue as it just doesn't allow me to continue using FM for XML.

I'll appreciate any advice. Many thanks in advance,

Alex
