Support chuvash characters

[vovsemenv]

Hello, martians ! We would love to have chuvash language support in this font. For chuvash language we only need to add this 4 characters in addition to russian. Additional characters list:

• Ӑ ӑ
• Ӗ ӗ
• Ӳ ӳ
• Ҫ ҫ

Find out that maybe it's already supported current subset. I will check that again.

I see similar glyphs in readme but in google fonts they dont work

Releasing the Cyrillic on GF is in progress: https://github.com/evilmartians/mono/pull/22

Thank you for the issue!

Can we also re-use Cyrillic Ҫ in Latin Ç, which is used in Catalan? In some fonts they look very similar

[vovsemenv]

@ai yeah it's totally can be reused. At the first glance Latin Ç looks like perfect fit. Cyrillic one looks little bit weird for me because in all books bottom part was more round shaped (i mostly remember it from school program literature)

P.s i will discuss with my native-speaking friends

Hi @vovsemenv, I work in the GF team, I'm preparing Martian Mono for an upgrade, your request comes at the right time! I added the glyphs needed for chuvash language support, you can find the good exports on my fork: https://github.com/emmamarichal/mono

Tell me if it's looks ok, so @romashamin can merge my PR.

@vovsemenv it might be not easy to open Glyphs file so I made a little preview for you:

What do you think?

[vovsemenv]

@romashamin OMG this looks perfect !!!! Thank you for the good work 😻

[romashamin]

Great then! @vovsemenv thank you for your help 🙌

@emmamarichal, I believe we’re good to go!

Note to self, the Es with a descender should have their regular form with the straight tail. Also, the font should contain localized character variants with a cedilla in Esdescender-cy.loclCHU and esdescender-cy.loclCHU glyphs along with the next OT feature:

script cyrl;
language CHU;
lookup locl_cyrl_1 {
	sub Esdescender-cy by Esdescender-cy.loclCHU;
	sub esdescender-cy by esdescender-cy.loclCHU;
} locl_cyrl_1;

Will be fixed in 1.1.

In Helvetica, the Chuvash glyph has a different shape from the regular cedilla.:
