iso-8859-2 characters input in GtkEntry widget

[Paul Ortyl <ortylp 3miasto net>]

Short question, because I could not find answer anywhere else:

Does anyone know how to force app linked with gtk+-1.2.10 to allow input of
iso-8859-2 characters into GtkEntry widget (iso-8859-1 works) various
combinations of enabling gtk, gdk locale with LC_ALL and LANG set to pl_PL
gave nothing.

TIA
        Paul
