UTF-32 encoding.

Template Parameters

CharType

Type for storing 32-bit UTF-32 data. Default is unsigned. C++11 may use char32_t instead.

Note

implements Encoding concept

For in-memory access, no need to concern endianness. The code units and code points are represented by CPU's endianness. For streaming, use UTF32LE and UTF32BE, which handle endianness.
