[Debian-handbook-translators] Broken builds, fr-FR, pt-BR and zh-CN

[Petter Reinholdtsen]

I did a test build of the HTML edition of all languages on weblate, and
discovered three of the languages were failing to build.

I was able to fix the fr-FR and pt-BR translations, but the zh-CN one is
too far away from any language I know for me to fix.  This is the build
error I get when running "bin/build-html --lang=zh-CN":

        Merging zh-CN/05_packaging-system.po >> en-US/05_packaging-system.xml -> tmp/zh-CN/xml_tmp//05_packaging-system.xml

not well-formed (invalid token) at line 4, column 278, byte 607:

Anyone got any clue how to fix this?
