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.

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 ...
In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined (built into the markup language) or explicitly declared in a Document Type Definition (DTD). The format is the same as for any entity reference: &name;

The tables below list the number of bytes per code point for different Unicode ranges. Any additional comments needed are included in the table. The figures assume that overheads at the start and end of the block of text are negligible. N.B. The tables below list numbers of bytes per code point, not per user visible "character" (or "grapheme ...
It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that a UTF-8-encoded file using only those characters is identical to an ASCII file.
It is the most-used single-byte character encoding in the world. Although almost all websites now use the multi-byte character encoding UTF-8 , as of December 2024 [update] 1.1% [ 4 ] of websites declared ISO 8859-1 which is treated as Windows-1252 by all modern browsers (as required by the HTML5 standard [ 5 ] ), plus 0.3% declared Windows ...
