Should case repair keep O'tkir and o'g'li lowercase after the apostrophe, as Uzbek writes them? (O'TKIR SOBIROV gives O'Tkir) #1274

Uzbek Latin writes the letters oʻ and gʻ with an apostrophe, officially the okina U+02BB, in practice often the typed '. Case repair (R4) capitalizes after an apostrophe inside a word, as O'Brien needs. So it capitalizes inside the Uzbek letter. Measured on master b76f278:

O'tkir and O'Brien have the same shape: a capital O, an apostrophe, a consonant. The letters alone can't tell an Uzbek letter from an Irish elision. #1214 settled the Cyrillic case by the vowel after the apostrophe. It left the Latin shape open (DEM'YAN → Dem'Yan, Kikuyu NG'ANG'A → Ng'Ang'A, Hawaiian KA'AHUMANU → Ka'Ahumanu, recorded in decisions/R4).

The question: is there a signal, or is this accepted?

• A listed exception: o'g'li, qizi (the patronymic markers, already vocabulary), and the g'/o' names as masks.
• An apostrophe after a letter other than an initial O/D/L: lowercase after it. That would fix Sa'Dullayev, Ng'Ang'A, Ka'Ahumanu and Dem'Yan, but not O'tkir or G'ofurov.
• Under locales.TR_AZ only.
• Accepted as it is, the U+02BB spelling being the remedy.

Measured population: opensanctions-parliaments' Uzbek chambers (uz_legislative_chamber, uz_senate) write these in mixed case already, so they measure what repair would do to an uppercased copy.
