Hi Michael,

Thanks for reporting this. unicode-math gets its definitions from the 
STIX fonts, and the complete list (some 2400 symbols) has been 
partially invented to cope with the new glyphs that have never had TeX 
names. Some of the new names are not always perfect and we need 
feedback like this to ensure that good names have been chosen.

In this case, \ac is defined as U+223E; we'll change the name to 
something more proper like \invlazys.

For now just comment out or change the line in unicode-math-table.tex 
that deals with this and it'll be fixed in the next update.

Thanks,
Will
