  Depends on the encoding used by GtkEntry or GtkText, if this is
restricted currently to ISO-Latin-1 then a simple routine can be used
to convert:
    - from ISO-Latin-1 to UTF8 in between 1 and 2
    - from UTF8 to ISO-Latin-1 between 5 and 6
I have such routines isolat1ToUTF8() and UTF8Toisolat1() in libxml2
(they are also present in libxml1 with a different signature but they are
 not exported publicly so that something I may be able to fix before the
 final 1.8.12 release).
But maybe since GTK2 will be heavilly UTF8 based it's better to introduce
such conversion routines at the GTK level and not rely on libxml for this.
