Why not use?

 result = g_convert (string, -1, "UTF-8", "ISO-8859-1", NULL, NULL, NULL);

(result will be NULL if conversion failed; pass in &error for the last
 argument if you want a string for the reason for failure.)

Frequently, you'd want g_locale_to_utf8() instead of this, however,
unless you *know* that the source encoding is ISO-8859-1.
