Somehow all occurrences of the entity (non-breaking space) were changed to   (moved); in Tor Launcher's network-settings.dtd files.
I am not sure where things went wrong, but at this point the strings on Transifex are bad. They were correct prior to commit 7ffed96e51cdb4207980810ece44c58d2d25fda6
Remove the non-breaking space characters (which arguably makes the text a little harder to read).
Fix the files in Tor Launcher and hope the problem does not recur.
Fix the strings via transifex.com and hope the problem does not recur.
Mike, do you have any theories about how this happened and how we can avoid it in the future (and what should we do right now)?
