Converts a string from one character set to another, possibly including fallback sequences for characters not representable in the output.
Note that it is not guaranteed that the specification for the fallback sequences in
fallback will be honored. Some systems may do
an approximate conversion from
to_codeset in their
iconv functions, in which case GLib
will simply return that approximate conversion.
Note that you should use 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_with_iconv 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.)
