When converting from .docx to plain text using a headless LibreOffice, the <w:noBreakHyphen/> becomes a 0x1D character. There's an example document at <http://source.data.ox.ac.uk/vacancies/103036/0000217976.docx>. When viewed in Writer the document is missing a visible hyphen at this point.
Thank you very much for your bug report! (In reply to comment #0) > When viewed in Writer the document is missing a visible hyphen at this point. If I understand correctly, the point in question is in "such as multi-national companies which sponsor research at the University" under point 4 of "Essential" under "Selection criteria" (page 5). This sentence should read "... multi-national companies ...", but Writer displays this with a special kind of space as "... multi national companies ...". REPRODUCBLE with LibreOffice 3.6.1.1 (Build ID: 4db6344) on MacOS X 10.6.8 (Intel).
@Miklós Vajna: Hello Miklós, please take a look at this bug report about a problem with OOXML (.docx) import. I hope it should be rather easy to fix this issue, because it is a single well-defined problem. It is still present in LibreOffice 3.6.1.1. Thank you very much in advance!
That character imports correctly and exports as the plain hyphen in 4.0.3.
