Expand description

Converts a string from one character set to another.

Note that you should use [iconv()][crate::iconv()] for streaming conversions. Despite the fact that bytes_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 convert(), convert() or 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.)

Using extensions such as “//TRANSLIT” may not work (or may not work well) on many platforms. Consider using g_str_to_ascii() instead.


the string to convert.


name of character set into which to convert str


character set of str.


If the conversion was successful, a newly allocated buffer containing the converted string, which must be freed with g_free(). Otherwise None and error will be set.


location to store the number of bytes in the input string that were successfully converted, or None. 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 ConvertError::IllegalSequence occurs, the value stored will be the byte offset after the last valid input sequence.
