Make it possible to display non ASCII even on Linux console

[kachick]

No kmscon as written in https://github.com/kachick/dotfiles/issues/660, the Linux console displays Japanese file names as Tofu.

How about using bdf fonts or converting ttf to bdf and psf?

Viewing https://github.com/emurenMRz/bdf_view for largest size of https://github.com/coz-m/MPLUS_FONTS/blob/c47fd4ff0a604d1517625a0f3d67e6d64e12d585/obsolete/mplus_bitmap_fonts-2.2.4.tar.gz mplus_j12r.bdf, it is much little 🤔

Unifont – 8×16、16×16 (Unicode のカバー率が最も高いフォント) (bdf-unifontAUR)

PSF: A specialized PSF 1 console frame buffer font consisting of 512 glyphs for use with APL, A Programming Language, in console mode (single-user mode on GNU/Linux, etc.), mainly to support GNU APL: Unifont-APL8x16-15.1.05.psf.gz (4 kbytes)

The other advantage is that PSF fonts can store the whole UNICODE character set, although consolefonts have maximum 512 glyphs usually.

Ah... I didn't know, this looks like a PSF restriction...?

So converting cannot resolve this problem. And if I want to completely avoid Tofu, I should remove non English and emojis...

They also have to have either 256 or 512 glyphs.
