When exporting to Word, text blocks (requirement descriptions for example) always export the spaces between words as non-breaking spaces. This is a variation on the standard (0x20) space that Word can use. Word basically sees the entire text block as a single word - and thus wraps very oddly.
The workaround is to "search and replace" the new document - replacing the special character with a normal space character.
The special character does not seem to be in the input text - as I can "fix" it in Helix, and it still comes out as non-break when I export again. Is there a setting or special field in the template?
