Hi,
As my former boss is a Japanese, so I have to make games in Japanese, I remember I've came up a function of using bitmap font to display Japanese, and the IDE itself does show correct font when using correct font, but I stuck when we have to make multi language translation, because the IDE can't load/save the unicode when I tried it. So I rewrite game with similar logic in Love2D instead.
But I've start doing the side project now, I can use whatever I want, GLBasic is still a nice choice, since compile to webassembly is a nice addition to me.
