Is there any character like that?

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?

there is at least ch to be seen as the "op"-combination. To be exact, it would be 2 characters composing 2 letters, but the ch is considered as 1 character by many people.
