I think I found something to narrow down that problem:
The font used by Pango in the not working Android 4.3 is
the MotoyaLMaru font (*), if I copy that font to the working Android
4.0.3(who uses a Sans fallback), then Pango will use it instead of the
working one.

So I think I have to investigate why Pango uses that font as default
and/or why setting the language to "ca" changes the font to a one that
works and setting the language to "fr" doesn't, and/or find the way to
force Pango to use a custom font that Tux Paint provides. 

Thanks for any comments

(*) The MotoyaLMaru font was designated to support Japanese language,
and lacks many of the European accented letters
