Character and String Processing
Overview
As described in The Unicode Standard, the Internationalization Module uses the UTF-16 -character encoding form for the internal representation and manipulation of multilingual text. In UTF-16, each 21-bit Unicode code point is represented using one or two 16-bit code units.
The character and string processing classes of the Internationalization Module provide the ability to create and manipulate UTF-16 strings. This chapter describes how to:
examine the character traits of an individual code point with RWUCharTraits; for example, its case, its direction of display, or whether it is a whitespace characterrepresent and manipulate UTF-16 strings with RWUString, and substrings with RWUSubString and RWUConstSubString
