    I don't know this list. Could you please give more information?

    Sounds reasonable to me. But I don't know any font that has initial
    and medial glyphs for U+0649. Do you?

    I do not believe this:
    Is there any evidence/proof that initial and medial glyphs exist?
    How should they look like? Are there any fonts that contain such glyphs?

    > U+0649 (ALEF MAKSURA) is used in the Arabic Qur'an in the middle of words.

    No, not U+0649 but U+0670.

    I do not believe this. In Arabic, initial and medial glyphs always have
    two dots. (The letter with hamza has no dots.)

    Exactly. But I was asking about "dual-joining", i.e. initial and medial

    So far, I haven't seen evidence/proof that *initial* and *medial*
    forms of letter ya *without dots* (and without hamza) exit in Arabic.
    Such may exist in Uighur - but I don't know enough about Uighur.

    And it remains the question of U+06BA: Show me a left-joining glyph!
