Character encoding in source code, input-output and GUI is know mess. There is Ada 2022 library that provides high level API to process text information, see
https://github.com/AdaCore/VSS
You can try to use Virtual_String everywhere, and do encoding conversion only to get/pass text from/to Gtk+ or input-output streams.
Note, if you want to write characters outside of the ASCII range in the source code you will need to use UTF8 for source files and provide -gnatW8 switch to compiler. It may breaks compilation of the old code sometimes :(
