Thanks David,

Yes the mathvariant values are there. What I meant is that the arabic 
unicode code blocks is not mentioned, so it's not clear how to implement 
these values. Especially the paragraph

"Certain combinations of character data and mathvariant values are 
equivalent to assigned Unicode code points that encode mathematical 
alphanumeric symbols. These Unicode code points are the ones in the SMP 
Mathematical Alphanumeric Symbol range U+1D400 to U+1D7FF, listed in the 
Unicode standard, and the ones in the Letterlike Symbols range U+2100 to 
U+214F that represent "holes" in the alphabets in the SMP, listed in 
Section 7.5 Mathematical Alphanumeric Symbols."

should mention the arabic block, I think. Should probably be done at 
other places too.
