WebA valid UTF-8 character can be 1 - 4 bytes long. For a 1-byte character, the first bit is a 0, followed by its unicode. For an n-bytes character, the first n-bits are all ones, the n+1 bit is 0, followed by n-1 bytes with most significant 2 bits being 10. The input given would be an array of integers containing the data. WebThis has since been expanded to 32 bits. The simplest encoding mapping this to 4 fixed bytes is called UCS-4. To represent these characters more efficiently, variable length encodings are typically used instead: UTF-8 and UTF-16.
