When I type diameter symbol Ø with "Alt + Numpad 0216" I get random japanese kanji as output.

This weird behaviour happens only when adding a new Globl Variable.

Obviously I have not any japanese keyboard nor japanese language.

It is attached as well.

The weirdest thing is that it started all at sudden: the first two Ø ("Ø foro min fila 1" and "Ø foro magg fila 2") were obtained regularly.A
