I just worked with this, and made some symmetrical definitions: see the  
attached modified files.

\setcharactermirroring[0,1] works in both uni- and bi-directional text --  
note that each bracketpair is inside of its respective directional context.

However, for the FIRST occurence of a bracket-pair in a bidi paragraph it  
does not behave as expected.

It may be that the second invocation of \setcharactermirroring does not  
immediately override the last. Maybe we need a \flush or  
\clearsetcharactermirroring command?

Best wishes
Idris
