searching for ‘unicode’ brings up some hits …
This one might explain what’s going on:
This depends on the kicad font - Unicode is not supported, only a very few glyphs from the Hershey font. If you wish to have text in other languages you may need to produce a bitmap, import with the “bitmap2cmp” tool and place it as a graphic on the appropriate layer. The only other alternative at the moment is to use another software to edit the Gerber file and place your text as PCB fabricators do.
