What constitute? an abstract character?

[Ken Whistler]

Not an interesting question, actually.

The units relevant to count in text, depending on what you are doing, are:

code units

code points

user-perceived characters (and other higher-level constructs which may 
be orthography-specific)

"abstract characters" are an artifact of the formal encoding process. 
They are really only "counted" by character encoding committees, not by 
software processing text strings.
