True, but this may be part of the source code, and that backslash was not separated from the translation unit, so we cannot remove it in translations without breaking the code. If the code is fixed in a beta branch, updated messages without these backslahsed would have to be uploaded again to TWN (where they will all still need review in all languages, even if they were just all modified without this backslash). Anthere should look at this in her repository for the ISA tool.
