Some specials characters are missing

[axoulc]

Hi,
I really like this font for my OLED screen. I need to display a price in EURO €. This symbol is missing for every size.
Is it possible to have it ?

Thanks in advance

If the fonts I use as input to this project have a Euro glyph, then it should be possible. If you wanted to try doing it yourself you could add it to:

profont/tools/src/generate.rs

Line 81 in e2002b2

let all_chars = basic.chain(extended).collect::<Vec<_>>(); // TODO: Do we really need to collect these?

and:

profont/font/src/lib.rs

Line 51 in e2002b2

const GLYPH_MAPPING: StrGlyphMapping =

Hi @axoulc I looked into this and unfortunately the source font I'm currently using does not have a Euro glyph. Also checked the alternate OpenType Bitmap version of ProFont on https://tobiasjung.name/profont/ but it does not have it either. Since this crate is just transforming the font into a form usable with embedded-graphics, adding new glyphs to the source font is currently out of scope of the project.

For reference these are the glyphs it does have:

Looking over the ProFont website some more there is a version "ProFont bitmap with €" for Macintosh. This is a classic Mac font suitcase stored in a resource fork. Using my MacBinary decoder I see the following:

Poking around in ResEdit I have confirmed € is present:

So it's possible this crate could be rebuilt to use this font, or at least retrieve the € from it. This is a fairly large amount of work though, and I'm not sure if/when I'll be able to get to it.

Ok, I nerd sniped my way into doing this, I'm about 80% done.

@wezm I didn't expect so much from you. Thanks in advance

[axoulc]

@wezm if I can help you for anything, just let me know ! ;)

All good so far, just working out some glyph positioning issues. Here's the WIP font atlas for 24pt (note € in the middle of the last line):
