Adding new characters to a typeface requires both design skill (because the new glyphs must be drawn) and technical skill (because the new glyphs must be added to the typeface’s font files and optimized). If you have these skills, I’d love to chat with you. If so, can you email me at gregveen@adobe.com? Thanks!

Thanks for the report! The browser/OS support details for Edge Web Fonts are outlined in the documentation. We don’t support every specific WebKit variant at this point, but that may change in the future.

(this is fixed now)

We hope to expand coverage in the future. In the meantime: some of the fonts do contain some Central/Eastern European characters. While we do not yet offer a way to browse/search the fonts by which languages they support, you can access all of the languages each font supports by using the “all” subset when loading fonts, instead of the default subset. So, when working with fonts and looking for Central European characters, please make sure to use the “all” subset. Check out the Subsets section of the documentation for more details.

While we don’t yet offer a way to browse/search the fonts by OpenType feature support, some of the fonts do have some OpenType features. Be sure to use the “all” subset (instead of the “default”) when loading fonts in order to get access to whatever OpenType features a font contains. Note also that not all browsers support OpenType features yet, but their support is growing. Check out the Subsets section of the documentation for more details on subsets.

I suspect that by “unicode support” you mean support for more languages than are covered by Latin1. Let me know if you’re asking about something else, if not, my reply above about Eastern European languages applies here, too. Thanks!
