@header CFCharacterSet
CFCharacterSet represents a set, or a bag, of Unicode characters.
The API consists of 3 groups:
1) creation/manipulation of CFCharacterSet instances,
2) query of a single Unicode character membership,
and 3) bitmap representation related (reading/writing).
Conceptually, CFCharacterSet is a 136K byte bitmap array of
which each bit represents a Unicode code point. It could
contain the Unicode characters in ISO 10646 Basic Multilingual
Plane (BMP) and characters in Plane 1 through Plane 16
accessible via surrogate paris in the Unicode Transformation
Format, 16-bit encoding form (UTF-16). In other words, it can
store values from 0x00000 to 0x10FFFF in the Unicode
Transformation Format, 32-bit encoding form (UTF-32). However,
in general, how CFCharacterSet stores the information is an
implementation detail. Note even CFData used for the external
bitmap representation rarely has 136K byte. For detailed
discussion of the external bitmap representation, refer to the
comments for CFCharacterSetCreateWithBitmapRepresentation below.
Note that the existance of non-BMP characters in a character set
does not imply the membership of the corresponding surrogate
characters. For example, a character set with U+10000 does not
match with U+D800.
