    // Gjs wrapper for g_convert_with_iconv()

Converts a string from one character set to another.

Note that you should use GLib.iconv for streaming conversions. Despite the fact that @byes_read can return information about partial characters, the g_convert_... functions are not generally suitable for streaming. If the underlying converter maintains internal state, then this won't be preserved across successive calls to GLib.convert, GLib.convert_with_iconv or GLib.convert_with_fallback. (An example of this is the GNU C converter for CP1255 which does not emit a base character until it knows that the next character is not a mark that could combine with the base character.)


the string to convert


the length of the string, or -1 if the string is nul-terminated (Note that some encodings may allow nul bytes to occur inside strings. In that case, using -1 for the len parameter is unsafe)


conversion descriptor from


location to store the number of bytes in the input string that were successfully converted, or null. 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 #G_CONVERT_ERROR_ILLEGAL_SEQUENCE occurs, the value stored will the byte offset after the last valid input sequence.


the number of bytes stored in the output buffer (not including the terminating nul).


If the conversion was successful, a newly allocated nul-terminated string, which must be freed with Otherwise null and @error will be set.
