23? Or 21? AIUI if the 'least-count' is 1 its 21 If its 8 its 24 If its 16 its 32 More pertinently if the number of bits signifies, whatever is the sense of the word 'abstract'? > or code points, representing (among other things) characters, and numbered > from U+0000 to U+10FFFF. Any UTF is, by definition, a transformation from > such abstract code points to sequences of machine words or bytes (and vice > versa). What's your point? I think its more useful to think of data transformations between formats Rather than calling one format more abstract than another -- https://mail.python.org/mailman/listinfo/python-list
