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.).
