what is the encoding of text in gtk?

["Ben Wing" <ben 666 com>]

hello, i'm the main author of the i18n support in XEmacs and i'm trying to fix
up the gtk support in XEmacs to be i18n-correct.  unfortunately, i didn't write
the support (that was done by Bill Perry), and i don't understand gtk very well.
i couldn't find any documentation on how strings are encoded.  however, it
appears from reading the source code that strings in gtk 2 are in utf-8 and
strings in gtk 1 are in the locale-specific encoding.  is this correct?  in all
cases?  all api's? (e.g. gdk_*, gtk_*, gnome_*, etc.) does this include
selection data, drag-n-drop data, etc.?  any specific weirdnesses i should know
about?  finally, is it correct to check gtk_major_version >= 2 to determine
whether to use utf-8?

thanks for your help.  please make sure my email is in the to: or cc: since i'm
not on this list.
