Detailed Description

template<class CodeUnitType>
struct fe::enc_traits_utf16< CodeUnitType >

UTF16 encoding traits.

A utility class to read UTF16-encoded character data.

Note:

Don't use functions of this class other then documented ones directly. The class is intended for use as a specialization for fe::UTF32Iterator template.
