There is a misunderstanding here: the square root character *does* have the mirrored property, just like parentheses. If the RTL glyph is not available for this character, it is a pure font issue. > >Third, I am still searching for the right font but can't > find it yet.

The fact that square root is declared to be "mirrored" by Unicode means that: 1) In an ideal world, all fonts should have *both* the LTR and RTL glyphs and select the proper one according to the bidi context; 2) In a cruel world, any font should have *either* the LTR or the RTL glyph, whichever is considered more useful by the font designer. So an OpenType (ot even TrueType) font designed for Arabic could and should have a RTL square root right *now*. Of course, it cannot have *also* the LTR glyph; not until "smart" fonts will be smart enough to handle this. Unfortunately, Munzir Taha's question remains: I have looked in all the Hebrew and Arabic *TrueType* fonts I have, but the square root is either missing or it is LTR. _ Marco
