Luatex does not mirror characters that has a Bidi_Mirrored property when
the text direction is set to RTL (TRT in Aleph), according to 
http://unicode.org/reports/tr9/#Mirroring, the different types of
parenthesis that has Bidi_Mirrored property should be mirreored in RTL
mode, but this isn't what I get. Is this a bug, feature, or am I missing
some thing?

Thanks,
 Khaled
