Missing smallcaps African letters

[brawer]

Currently, Noto Sans looks very uneven for African languages in small caps. Because the font doesn’t contain smallcaps designs for African letters, the Chrome browser (and other text rendering systems) fall back to lowercase. Can we add the missing glyphs?

For a longer example, see the Universal Declaration of Human Rights in Guinea Kpelle (scroll down a few pages for the small caps rendering). For later reference, I’m also attaching the HTML file used to generate this PDF.

Here are PDF files with the Universal Declaration of Human Rights in Guinea Kpelle, rendered with the current draft for the next version of Noto {Sans,SansMono,SansDisplay,Serif,SerifDisplay} {Regular,Italic} -- all possible Noto fonts.

Actually, this request is about adding small caps letters...

Look like this issue has been resolved. Please reopen if you have other thoughts

@nizarsq The ɛ, ɔ, ɓ, ɲ are still lowercase in the sample.

This issue and #362 could probably be replaced by a single issue about missing smallcaps in NotoSans, Noto Serif and Noto Sans Mono.
The rule of thumb is that all the Latin letters that have an uppercase-lowercase pair should have a smallcap as well. This is can be used for Cyrillic and Greek as well.
With this rule here are the lowercase characters that are missing smallcaps in Latin: ƀƃƅƈƌƒƕƙƚƞơƣƥƨƭưƴƶƹƽƿdžljnjǎǐǒǔǖǘǚǜǝǟǡǣǥǧǩǫǭǯdzǵǹȁȃȅȇȉȋȍȏȑȓȕȗȝȟȣȥȧȩȫȭȯȱȳȼȿɀɂɇɉɋɍɏɐɑɒɓɔɖɗəɛɜɠɡɣɥɦɨɩɪɫɬɯɱɲɵɽʀʃʇʈʉʊʋʌʒʝʞᵹᵽḁḃḅḇḉḋḍḏḑḓḕḗḙḛḝḟḡḣḥḧḩḫḭḯḱḳḵḷḹḻḽḿṁṃṅṇṉṋṍṏṑṓṕṗṙṛṝṟṡṣṥṧṩṫṭṯṱṳṵṷṹṻṽṿẇẉẋẍẏẑẓẕạảấầẩẫậắằẳẵặẹẻẽếềểễệỉịọỏốồổỗộớờởỡợụủứừửữựỵỷỹỻỽỿⅎↄⱡⱥⱦⱨⱪⱬⱳⱶꜣꜥꜧꜩꜫꜭꜯꜳꜵꜷꜹꜻꜽꜿꝁꝃꝅꝇꝉꝋꝍꝏꝑꝓꝕꝗꝙꝛꝝꝟꝡꝣꝥꝧꝩꝫꝭꝯꝺꝼꝿꞁꞃꞅꞇꞌꞑꞓꞗꞙꞛꞝꞟꞡꞣꞥꞧꞩꞵꞷꞹꭓ
These can be split in subgroups if you want to prioritize language support characters, transliteration characters, phonetic characters or historical characters differently.

Should there be new single issue for missing smallcaps in general?

[JonWFergus]

@moyogo that seems appropriate to make this a single issue, and to have subgroups, as some of those glyphs are much more common than others and could be prioritized.

A suggestion I'd make, since many of the missing glyphs you list are primarily used in transliterations of other languages into the Latin alphabet, is for one subgroup to focus in on the missing glyphs for IAST transliteration of devanagari, as those glyphs are quite common and relate to several Indian language transliterations (that relates to #362), while another subgroup could focus in on the missing glyphs for transliterations of Arabic and Hebrew. Those two subgroups would cover a decent number of the more commonly used missing glyphs you list above, then the more obscure ones could be covered last.

@moyogo I do not have any experience with font glyphs but would like to contribute and add the missing glyphs for IAST Devanagari.

How would I get started?
