ISO-8859-1 (Latin-1) is not ASCII.  It uses the 8th bit for non-ASCII
characters.  Latin-1 and UTF-8 are ASCII compatible if you stick to the
ASCII character set.

If you are saving data to file, it is much better to save it in unicode
format as UTF-8, and if you need to convert it, convert it when reading.
However, if you really think you need to convert to Latin-1, use
Glib::convert().

But what drew you to Latin-1?  If that is your locale encoding, it won't
necessarily be other people's locale encoding, and for that reason
saving data to file in the locale encoding is generally a bad idea, as
it is non-portable. However, if that is not an issue, you could use
Glib::locale_from_utf8().
