    Yes, although some fonts might display a box between the q and ꝫ.

    The individual ligatures have to be pre-implemented in the font, so if
    you want q+200D+A76B to display as a ligature you either have to
    create a font yourself and add the appropriate OpenType features, or
    else nag a font developer to put it in their font for you. In
    principle this mechanism does work with Latin text. For example, the
    Code2000 font implements a number of common ligatures which are
    triggered by means of ZWJ, e.g. <s+ZWJ+t> produces the "st" ligature.
    An alternative implementation might automatically generate an "st"
    ligature whenever "t" follows "s" unless broken by ZWNJ.
