A character is encoded as 1 or 2 bytes. A byte in the range 00–7F is a single byte that means the same thing as it does in ASCII. Strictly speaking, there are 95 characters and 33 control codes in this range. A byte with the high bit set indicates that it is the first of 2 bytes.
SBCS, or single-byte character set, is used to refer to character encodings that use exactly one byte for each graphic character.An SBCS can accommodate a maximum of 256 symbols, and is useful for scripts that do not have many symbols or accented letters such as the Latin, Greek and Cyrillic scripts used mainly for European languages.
In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
First-generation Japanese MSX models used a character set extended from the JIS X 0201 standard (which provided basic single-byte Roman and katakana characters), [3] [4] with hiragana, a few common kanji (accessed via the "graph" key), and various geometric symbols filling in the otherwise-unspecified codepoints.

Single-byte character sets including the parts of ISO/IEC 8859 and derivatives of them were favoured throughout the 1990s, having the advantages of being well-established and more easily implemented in software: the equation of one byte to one character is simple and adequate for most single-language applications, and there are no combining ...
ISO/IEC 8859-7:2003, Information technology — 8-bit single-byte coded graphic character sets — Part 7: Latin/Greek alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. [2] It is informally referred to as Latin/Greek. It was designed to cover the modern Greek language. The ...
5 for an isolated case inside a run of single byte characters. For runs 2 + 2 ⁄ 3 per character plus padding to make it a whole number of bytes plus two to start and finish the run 6 2 + 2 ⁄ 3: 2–6 depending on if the byte values need to be escaped 4–6 for characters inherited from GB2312/GBK (e.g. most Chinese characters) 8 for ...
