Bug in Apple Devanagari Font

A poster in the Apple Support Communities has pointed out that the font Devanagari Sangam used for iOS (and also available in OS X 10.7 and higher) produces the wrong glyph for the sequence r + virama + h. For some reason it generates the glyph for the sequence r + virama + h + e instead.

The font Devanagari MT, which is the default for OS X, does not have this problem, so using that is a fix
