D92 UTF-8 encoding form: The Unicode encoding form that assigns each Unicode scalar value to an unsigned byte sequence of one to four bytes in length, as specified in Table 3-6 and Table …

Unicode characters are represented by U+## (where ## is the hex value of the character encoding data) and all 1-byte characters match the ASCII character encoding:

Encoding to Represent Characters An encoding is needed to represent the displayed/printed/stored value of characters Either in char variables or in strings

Variable-length encoding that uses 1, 2, 3, or 4 bytes to encode a Unicode character/code point. Q. Given a bunch of bytes, can we tell if it represents an encoding of a character set?

In spite of some relicts of chaos in the real world, the problem of character encoding has been solved almost exhaustively, esp. compared to the previous 8-bit solutions.

UTF-8 is the most widely used CES. 1. ACR specifies collection of characters, i.e. a , !, ä and ‰. 2. CCS specifies numeric codes, i.e. ISO 10646 uses 97, 33, 228 and 8240 (0x2030) for the …

Each code plane consists of multiple code blocks, each is one of several contiguous ranges of numeric character codes with an assigned name. BMP contains characters for almost all …
