The dot that you have entered is 0x00B7 which is periodcentered. The cdot 
maps to 22C5.

Everything works fine if you use a unicode math font (cambria or xits). In 
LM, there is a bug in the mappings. For some reason 00B7 is mapped to 
squaresmallsolid in tex-ma. I need to check why that definition is there 
before determining how to fix it (which is relatively easy).

OT: Is there a timeline for LM OpenType Math?
