    function Convert_Error_Domain  return GQuark;
| Return the error domain associated with Glib.Convert.

| Convert a string from one character set to another. Str: String to convert Result: String converted, if no error. To_Codeset: Name of character set into which to convert Str From_Codeset: Character set of Str. Bytes_Read: Number of bytes in the input string that were successfully converted. Even if the conversion was successful, this may be less than Len if there were partial characters at the end of the input. If the error Illegal_Sequence occurs, the value stored will the byte offset after the last valid input sequence. Bytes_Written: Number of bytes stored in the output buffer. Error: Location to store the error occuring, ignored if null. Any of the errors in Convert_Error_Domain may occur.

| Convert an escaped UTF-8 encoded URI to a local filename in the encoding used for filenames. URI: A uri describing a filename (escaped, encoded in UTF-8).
