Steps to reproduce:

1. In Writer, insert a string in a language that uses saltillos to indicate glottal stops, like “Rukorbꞌaal tzꞌihbꞌanik poqomam qꞌorbꞌal” (Poqomam, a Mayan language.)
2. Go to Format > Text and select “Cycle Case”, “UPPERCASE”, “lowercase”, “Sentence case” or “Title case”.

Result:

The saltillos stay the same, even if UPPERCASE was selected.

Expected result:

The saltillos are transformed along with the rest of the letters.

The saltillo is an apostrophe-like *letter* of the Latin alphabet, and is bicameral, meaning it has uppercase and lowercase versions (U+A78B and U+A78C respectively).
