We successfully disunified YOGH from EZH and S and T WITH COMMA BELOW from
S and T WITH CEDILLA.

And therefore most fonts are useless for the African languages. To my mind
the florin sign does not appear in the UCS.

No, we should fix the character sets.
The following disunifications are, in general, still under discussion:
* COPTIC to be disunified from GREEK
* CYRILLIC LETTERs KU, WE, to be disunified from LATIN LETTERs Q, W
* FLORIN SIGN to be disunified from LATIN LETTER F WITH HOOK
* LATIN LETTER TONE THREE to be disunified from CYRILLIC LETTER ZE
* LATIN LETTER TONE FOUR to be disunified from CYRILLIC LETTER CHE
* CYRILLIC LETTER EN WITH TAIL to be disunified from CYRILLIC LETTER EN
* IPA Greek letters to be disunified from Greek letters.
Of them, I suppose the FLORIN SIGN disunification might be considered
expensive to industry because appears in Apple and Microsoft code pages.
Pity about the Africans, in that case. Unless we help them by adding a
LATIN SMALL LETTER AFRICAN F WITH HOOK which would case map to the LATIN
CAPITAL LETTER F WITH HOOK.
