Class Poco::UTF32Encoding

Library: Foundation
Package: Text
Header: Poco/UTF32Encoding.h

Description

UTF-32 text encoding, as defined in RFC 2781.

When converting from UTF-32 to Unicode, surrogates are reported as they are - in other words, surrogate pairs are not combined into one Unicode character.
