Web22 jul. 2009 · The UTF-8 encoding is variable-width, ranging from 1-4 bytes, with the upper bits of each byte reserved as control bits. The leading bits of the first byte indicate the total number of bytes used for that character. The scalar value of a character's code point is the concatenation of the non-control bits. WebUTF-8 is variable width character encoding method that uses one to four 8-bit bytes (8, 16, 32, 64 bits). This allows it to be backwards compatible with the original ASCII Characters 0-127, while providing millions of other characters from both modern and ancient languages.
