Some letters used in Latin transcription of Pan-Sahelian scripts are still missing in Unicode:
Prove it.
Is there a proposal to include them, as they are needed for case folding and capital transcrtiption?
Not till you prove it.
I can identify immediately these two ones that would be needed on Pan-Sahelian keyboards:
U+027E LATIN SMALL LETTER R WITH FISHHOOK U+???? LATIN CAPITAL LETTER R WITH FISHHOOK
U+0266 LATIN SMALL LETTER H WITH HOOK U+???? LATIN CAPITAL LETTER H WITH HOOK
But there are some other Latin letters that don't have their uppercase version. As well there are missing letters like R STRIKED (not the Rx symbol)
