Feature Request: Full width character support?

[cirdanlunae]

Is it possible to see full width character support in the extended .fnt files? These characters are used in vaporwave quite frequently, such as this example:

「３０,０００ Ｓｑｕａｒｅ Ｍｅｔｅｒｓ」 by Ｓｐｏｒｔ３０００

I looked online and from what I found, League Spartan does not support these characters by default. Not sure if there's a way to get support for them. Outstanding work on this Rockbox theme by the way--I can see this becoming the go-to theme for the community!

Edit: Here's an image of how it looks currently
