WebLetters use 2 bytes no matter what: “H” is 0x48 in ASCII, and 0x0048 in UCS-2 Encoding is simple. Take the codepoint in hex and write it out in 2 bytes. No extra processing is required. The encoding is too simple. It wastes space for plain ASCII text that does not use the high-order byte. And ASCII text is very common. WebFeb 21, 2024 · Unicode is a 21-bit code set and 4 bytes is sufficient to represent any Unicode character in UTF-8.

The first two characters are always "U+" to indicate the beginning of a code point. They are followed by the code point value in hexadecimal. At least 4 hexadecimal digits are shown, prepended with leading zeros as needed.

WebIn practice, the Unicode standard uses numbers in the range 0 to 1,114,111 to encode all the world’s characters, with the result that it needs just 21 bits to encode the full range.
