 * \brief Fallback implementation for not well-formed diagram files
 *
 * If all files produced by dia were good XML files, we wouldn't have to do 
 *  this little gymnastic. Alas, during the libxml1 days, we were outputting 
 *  files with no encoding specification (which means UTF-8 if we're in an
 *  asciish encoding) and strings encoded in local charset (so, we wrote
 *  broken files). 
 *
 *  The following logic finds if we have a broken file, and attempts to fix 
 *  it if it's possible. If the file is correct or is unrecognisable, we pass
 *  it untouched to libxml2.
 * @param filename The name of the file to check.
 * @param default_enc The default encoding to use if none is given.
 * @param ctx The context in which this function is called
 * @return The filename given if it seems ok, or the name of a new file
 *          with fixed contents, or NULL if we couldn't read the file.  The
 *          caller should free this string and unlink the file if it is not
 *          the same as `filename'.
 * @bug The many gzclose-g_free-return sequences should be refactored into
 *       an "exception handle" (goto+label). At least for people who think goto is
 *       better than this. I dont. --hb
