Well, whether apps support it or not is really up to the app.
GLib provides a range of facilities for codeset conversion:

 g_convert(), g_io_channel_set_encoding(), g_get_charset()
 g_locale_to/from_utf8(), g_iconv(), ...

Which are considerably easier to use and more portable than
raw usage of iconv.

No, it isn't seamless. To be "seamless", GTK+ would have to override
dozens of libc functions, which would not be at all kosher.

g_locale_to_utf8() usually provides a very easy way of doing

In some cases, there are GLib functions that wrap the system
function and do the conversion for the app; g_strerror() and
g_date_strftime() come time mind.
