Character Sets: Implementation of character sets in Scheme.

lang/scheme/code/ext/strings/char_set/
A character set is, as its name might suggest, a set for storing characters. Such sets are often particularly useful in string processing applications. The reason for treating sets of characters in a special manner is that until the advent of UNICODE and ISO ???, character sets only contained a maximum of 255 characters and so this fact could be taken advantage of in an implementation. The usual approach being to store a character set as a bit set.
