FOSS gamedev and creative worlds

Hello, i'm a newbe on minetest

i try to run minetest on bi-G5 under Debian with AZERTY wireless usb Keyboard (who work perfecty on console)
I compile the last 0.49 without any pb.

My pb is that i can type any things on start interface ... i show crusor move but any char !!!

Could anyone help me ?

Thanks a lot
Dody

Maybe a missing font?

maybe but i don't see any error about font on console from i execute minetest or in a specified logfile ...

In fact if a type a "World name" and i valid i have a "Character conversion failed! [minimal]" in world list ...

Have you a way to verify fonts ? or a other idea ?
Thx
