This got added in Unicode 4.1 ie long after MathML.


Yes I need (urgently) to update the tables in
http://www.w3.org/2003/entities/iso9573-2003doc/overview.html
(and mathml3 will (I assume) use those tables either by copying or
reference)

jmath actually got added to unicode as a more or less direct result of
pressure from these quarters (I managed to find a published paper using
j and jmath unaccented in the same paper)

there is a slight question as to what jmath should point to,

imath points to U0131 (which is really a textual dotless i, mainly for
Turkish) rather than to the mathematical alphabets in plane 1.
this of course was because at the time, that was all there was.

jmath points to j.

Clearly jmath should change but should imath?, or should jmath point to
237 to match imath.
