This does not mean, that the data structure representing a sequence of 
"letters" has to follow exactly the "working" you cited above. That 
data structure must only enable it efficiently. If a requirement for 
sequences of letters is, that a sequence `s' of letters indexed by some 
natural number `n' gives the letter `s[n]' and that is not efficiently 
possible, than unicode and its "workings" are as maldesigned as the 
alphabet Gutenberg has to take to produce books:

take randomly an ancient book `b' and randomly a letter `c'. Then try 
to verify that `b[ 314.159] == c'. Of course you are allowed to read 
only one letter.
