I've been thinking about characters lately and have realized that
tolower, toupper, icmp, and friends should not be in a string library.
Those functions need an "alphabet" to be useful; not language, nor
locale...
In fact, the character itself must have alphabet information. Otherwise
a string like "ali & jim" cannot be converted to upper-case correctly(*)
as "ALİ & JIM". And the word "correctly" there depends on each
character's alphabet.
Similarly, two characters that look the same cannot be compared for
ordering. Comparing the 'x' of one alphabet to the 'x' of another
alphabet is a meaningless operation.

I'm not sure I really understand this, probably because I don't know
much about how Unciode works. I'm thinking out loud:
If "i", as you have in "ali", have the corresponding "İ" as upper case
wouldn't that be another character than the English "i"? If so, I'm not
sure I see the problem. If not, I see the problem.
