Hello, I have seen a strange behaviour with Firefox 68.10.0esr from testing and I wonder if the code of the DDTSS handles accented characters needs some fixing.
I did a new translation which automatically reused one sentence from the previous version which contained some accented letters, I also wrote a comment which contained an accented letter and both were displayed correctly until I hit the Submit button, but since I forgot a <trans> I got the page with the message: Translation not complete, still <trans> and now the accented letters were broken, so I fixed them and submitted the page again and everything is fine. I don't think that this translation has something special https://ddtp.debian.org/ddtss/index.cgi/it/translate/libpetsc64-complex3.13 and the encoding was wrong in the usual way: PETSc è il PETSc è il con in più con in più -- Daniele Forsi
