I meant that the codes for the mirrored integral, etc., are exactly the same as the unmirrored symbols. The display software just mirrors them in RTL math zones. If you use OpenType, you used the 'rtlm' feature or shaping, as the characters warrant. This is the same thing as for mirrored characters that have mirrored character counterparts. An open paren is U+0028 whether it's mirrored or not.
