Examining math documents and math publishers� lists, we have
found errors in the math-property assignments for the characters listed in the
table below. The �math� column gives whether we think the character should have
the math property, the �GC� column lists its current general category, the
�TODO� column lists the proposed action, the �Reason� column gives the source
for the change and the �Name� column gives the Unicode name. BB stands for
Barbara Beeton of the American Mathematical Society (AMS).
