Is there any character like that?

[BessAgritianin]

Is there any character in the VM that is generally thought as 1 character but some people believe it to be 2 distinct characters with very subtle differences?

I would rephrase your question:
 "Is there one character that is  definitively singular in identity, without representing anything beyond itself?"
From a layperson perspective (like we all obviously are), characters appear to have fixed meaning. But is it so?
My humble experience teaches me- not.
