It's equivalent to have partially transparent pixels

I still don't think on-the-fly scaling, especially complicated one is a
good solution to a problem.
I think the est way is to find a set of TrueType fonts with adapted
typefaces, render them to different sizes and add unifont as fallback.
We could use on-the-fly cached scaling for unifont fallback and so its
slowness will be less of a problem and may be better alternative than
time required to load multiple versions of unifont. Also quality in this
case is less of an issue too.

Chinese people are usually familiar with either pinyin or

Transliterating Arabic isn't good idea. It will make GRUB look like a
big SMS
But we don't speak of same issues either. The only issues is that
Japanese or Chinese may see a similar symbol with similar rendering but
from other language. It may be unnice but is understandable. If we
really care about right symbol I suggest to use glyph variant codes.
