MSX2(2+) Universal font editor v3.3, with drivers (Kun-Basic)

New Beta version 4.5b commited to GIT:

Beta version 4.5b:
Updates
- New 8x8 lens mode (for proportional viewing)
- Optimisations, Refactoring, Bug fixing
- Japan and Euro keyboard versions
- Japan and Euro 8x16 fonts

Tested in OpenMSX and WebMSX

PS: My keyboard matrix is changed for updated MSX2 to MSX2+ RUS.
Therefore, I found wrong working keyboard on Japan and European machines.
Keyboard was reworked and this program versions placed to repo (also with native system fonts 8x16).
Good luck! :)

Nice work @Dolphin101546015

Due to different keyboard mapping, the program (version 5.0) is really hard to use with a non-Russian keyboard, for example "H" for help becomes "[" with a US keyboard. Is there a chance to set the program to use different keyboard layouts?

I tried a little on a Japanese MSX but although in the left frame there is a Russian font, in the right frame it is a Japanese character which is displayed regardless of the selected character.

Version 5.2 in GIT now
