The upload module tries to turn the strings into bytes before passing
to EditString, but it combines bytes & strings causing an error. The
return value might be bytes or string, but the caller only expects a
string. Lets simplify this by sticking to strings everywhere and have
EditString take care of converting to/from bytes when reading/writing
the underlying files. This also avoids possible locale confusion when
reading the file by forcing UTF-8 everywhere.
