    In the proposal for "Old Hungarian":

    there is said on p.4:

    3. Directionality. The primary direction of writing
    is right-to-left, though some modern users have
    used left-to-right directionality. Old Hungarian is
    encoded as strong right-to-left script; directional
    overrides can be used where necessary. When the
    direction of characters is changed, they are mirrored,
    like Old Italic and other scripts. The characters
    do not have a formal bidirectional mirroring
    property, however.

    Does this imply that if directional override is used, and if the text
    contains any characters not encoded within the "Old Hungarian" block,
    they are mirrored as well even if these characters themselves are
    strong RTL or strong LTR?
    Especially, if the quotation marks U+201F and (proposed in N3531)
    U+2E33 are contained, is it definitive according to the standard
    including the bidi algorithm (which I admittedly have not studied in
    every detail) that these quotation marks are mirrored, appearing
    like U+201D and U+201E?
