RTL writing of latin and cyrillic scripts

Does anyone know if it’s possible to make some coding (or adding some open type features) of the latin/cyrillic scripts for right-to-left (RTL) writing.

AFAIK, this has not so much to do with the font, but rather with Unicode and the text engine where the font is used. You can set anything right-to-left, the software just has to support it.
