    Change in orientation of the glyphs that's based on the writing direction
    should not be encoded via character codes. If it can't be determined
    automatically by a layout engine (as for mirrored characters) then
    explicit markup would be needed.

    Change in orientation of glyphs that are used to express differences in
    meaning are a candidate for encoding via character codes (vz. Arrows,
    phonetic symbols, inverted A and E for quantifiers, etc.).
