This is a vowel length mark, see p. 5 and the chart on p. 13 of the proposal L2/23-024.
I think this should be gc=Lm, and in PropList.txt, should have the Diacritic and Extender properties (like U+02D0).
The proposal bundles U+11DDA with it. For that one I don’t know whether it is more appropriate to treat it as a letter that is a glottal stop or as modifier that does mysterious syllable coda things. @Ken-Whistler, what do you think?

I don't think it (hecakā) is a vowel length mark, as contrasted with selā, which is. The glottal stop seems to be a full segment, although perhaps in restricted distribution. See the discussion of Kurukh and Brahui phonology on Wikipedia, for instance, which shows length distinctions (and in some cases nasalization distinctions) for vowels, which when marked in the orthography can be considered vowel modifiers and/or extenders, etc. But I think it is safest to just leave the glottal stop as Lo and treat it as another letter.

Does this change also require changes to LineBreak.txt?
Based on feedback from @eggrobin and @Ken-Whistler : - set gc=Lm (UnicodeData.txt) - set Diacritic and Extender (PropsList.txt)
