Such literal has type char16t and the value equal to ISO 10646 code point value of c-char, provided that the code point value is representable with a single UTF-16 code unit (that is, c-char is in the range 0x0-0xFFFF, inclusive).If the value does not correspond to a valid Unicode code point, or if the its corresponding code point is not representable as single code unit in UTF- N, it can still be specified by a numeric escape sequence with the value.E.g. u8 xff is well-formed and equal to char8t ( 0xFF ).
U16 Range C Code Point ValueAlthough not specified by the C or C standard, most compilers (MSVC is a notable exception) implement multicharacter literals as specified in B: the values of each char in the literal initialize successive bytes of the resulting integer, in big-endian zero-padded right-adjusted order, e.g. The standard library ud-suffix es do not begin with underscores. If the overload set includes a raw literal operator, the user-defined literal expression is treated as a function call operator X ( n ). If the overload set includes a raw literal operator, the user-defined literal expression is treated as a function call operator X ( f ). It is declared just like any other function or function template at namespace scope (it may also be a friend function, an explicit instantiation or specialization of a function template, or introduced by a using-declaration), except for the following restrictions. Must begin with the underscore: the suffixes that do not begin with the underscore are reserved for the literal operators provided by the standard library. This special syntax makes it possible to use language keywords and reserved identifiers as ud-suffixes, and is used by the declaration of operator if from the header complex. Note that using this form does not change the rules that user-defined literal operators must begin with an underscore: declarations such as operator if may only appear as part of a standard library header.
