Header: Poco/UTF16Encoding.h
Description
UTF-16 text encoding, as defined in RFC 2781.
When converting from UTF-16 to Unicode, surrogates are reported as they are - in other words, surrogate pairs are not combined into one Unicode character. When converting from Unicode to UTF-16, however, characters outside the 16-bit range are converted into a low and high surrogate.
