Docs (help and the dtinfo guides) are now always built using the
ISO8859-1 locale. To support UTF-8, our docbook needs to be updated
to something from this century, ideally this decade. In addition, a
conversion to XML would also be required as a result. So, until that
happens, use ISO8859-1 for docs.
However, other locale information, like message catalogs, resource
files, and the like are now converted to UTF-8.
All supported languages are now built by default on linux again.
