Full basic multilingual plane unifont #2535

Open Zipdox2 opened 2 days ago

My project involves displaying song titles and artists, and I'm looking for a font that has the most coverage. The most important characters for me are characters with diacritics, Japanese, and Cyrillic. The closest ones I've found are:\ Unifont, which doesn't have one font with all the characters,\ Efont, which doesn't have diacritics, and\ Boutique, which is too small (should be 15/16px tall).

Would it be possible to combine all the Unifont fonts into one big font? A 500kB monstrosity wouldn't really be a problem for me.

There is an external project which did this job: https://github.com/stgiga/UnifontEX/blob/main/UnifontExMonoU8G2.c

In general you can create u8g2 font files by yourself with "bdfconv.exe": https://github.com/olikraus/u8g2/blob/4b17158f4dd02ce386ac18f3fd30c20997a73871/doc/faq.txt#L255-L291

That solved my problem. But in my opinion there should be a pre-made full basic multilingual plane font. I guess I'll change my issue to that.

I guess most embedded systems don't have the memory for this

ESP32 development boards typically have 4MB of flash. The whole basic multilingual plane takes up 2034754 bytes.

Pruning combining characters and other non-characters seems like a good way to save a little bit of space, since they can't be rendered by U8g2 anyway. The original character will still be visible without diacritics or whatever. Here's what I've pruned so far:

These may also be pruned (in whole or parts)
