Returns the maximum length (in bytes) of a code point.īrings the mbstate_t object to an initial state. Returns 0 (the external encoding is not fixed-width). Returns 0 (not all conversions will yield a noconv result).
The class defines its functionality through its virtual protected member functions: In Translate in characters (public member function) out Translate out characters (public member function) unshift Unshift translation state (public member function)Īlways_noconv Return noconv characteristics (public member function) encoding Return encoding width (public member function) length Return length of translated sequence (public member function) max_length Return max length of one character (public member function) Public member functions inherited from codecvt (constructor) codecvt constructor (public member function) The external character type (encoded as UTF-8).Įnum type with the result of a conversion operation (see codecvt_base::result). The internal character type (encoded as UTF-16). The following aliases are member types of codecvt_utf8_utf16, inherited from codecvt: The multibyte sequence generated on conversions out shall be little-endian (as opposed to the default big-endian). To convert your input to UTF-8, this tool splits the input data into individual graphemes (letters, numbers, emojis, and special Unicode symbols), then it extracts code points of all graphemes, and then turns them into UTF-8 byte values in the. Mode Bitmask value of type codecvt_mode:Īn optional initial header sequence (BOM) is read to determine whether a multibyte sequence converted in is big-endian or little-endian.Īn initial header sequence (BOM) shall be generated to indicate whether a multibyte sequence converted out is big-endian or little-endian. The number '8' in UTF-8 means that 8-bit numbers (single-byte numbers) are used in the encoding. MaxCode The largest code point that will be translated without reporting a conversion error. The external character type in this facet is always char. This shall be a wide character type: wchar_t, char16_t or char32_t.įor 32bit-wide characters, conversions in of characters result in one UTF-16 code unit stored per wide character (as a 32-bit value). Template parameters Elem The internal character type, aliased as member intern_type.
