There seems some debate amongst digital classicists in whether to use U+2019 or U+02BC to represent the apostrophe in Ancient Greek when marking elision. (e.g. δ’ for δέ preceding a word starting with a vowel).
It seems to me that U+2019 is the technically correct choice per the Unicode Standard but it is not without at least one problem: default word breaking rules. I'm trying to provide guidelines for digital classicists in this regard. Is it correct to say the following: 1) U+2019 is the correct character to use for the apostrophe in Ancient Greek when marking elision. 2) U+02BC is a misuse of a modifier for this purpose 3) However, use of U+2019 (unlike U+02BC) means the default Word Boundary Rules in UAX#29 will (incorrectly) exclude the apostrophe from the word token 4) And use of U+02BC (unlike U+2019) means Glyph Cluster Boundary Rules in UAX#29 will (incorrectly) include the apostrophe as part of a glyph cluster with the previous letter 5) The correct solution is to tailor the Word Boundary Rules in the case of Ancient Greek to treat U+2019 as not breaking a word (which shouldn't have the same ambiguity problems with the single quotation mark as in English as it should not be used as a quotation mark in Ancient Greek) Many thanks in advance.
