Elem is a 32-bit type, one UTF-16 codepoint will be stored in each 32-bit character of the output sequence. This codecvt facet can be used to read and write UTF-8 files, both text and binary.
Template Parameters
| Elem | - | either Template:cpp, Template:cpp, or Template:cpp |
| Maxcode | - | the largest value of Elem that this facet will read or write without error
|
| Mode | - | a constant of type Template:cpp |
