i have proposed such a database file for consideration by the next utc meeting in
august. you will find a preliminary version in icu at
http://oss.software.ibm.com/developerworks/opensource/cvs/icu/data/unidata/Mirror.txt
there is an api in icu that provides this data: u_charMirror(). about icu, see

sometimes you can graphically mirror glyphs, but the best way to do this is to select
a variant glyph. italics are an example of where graphical mirroring does not work
(well).
