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).
