If you want mirror pairs, you should select only those pairs that are
mentioned in the BidiBrackets.txt file that is part of the Unicode
Character Database (UCD).  You can see them in Emacs by looking at
characters that have non-nil 'paired-bracket' property.

If you select any other pairs, they will look wrong in R2L text.
