I don't really think I understand what you want. K&R C had this, at
least for the ASCII subset of Unicode; it has arrays of characters and
you can access each character individually. If you want to know if the
third character in your array s is the Latin capital letter T, you
write s[2] == "T". If you want to know if it's a letter, you write
isalpha(s[2]). Naturally speaking, Unicode support is slightly more
complex, but it's still a matter of sequences of characters and
functions to query the properties. It's plain text, it doesn't have
XML's complex hierarchical features.
