UTF-8 vs Latin-1 (ISO-8859-1)

UTF-8

Unicode

The dominant encoding for the web. Variable-width (1–4 bytes). Fully backwards-compatible with ASCII. The default encoding for HTML5, JSON, and most modern protocols.

IANA Name: UTF-8
Byte Width: 1–4 bytes
BOM: EF BB BF
Introduced: 1993

Latin-1 (ISO-8859-1)

Legacy

Extends ASCII to 256 characters, covering most Western European languages. The first 256 Unicode codepoints map 1:1 to Latin-1 bytes. Largely superseded by UTF-8 but still common in legacy systems.

IANA Name: ISO-8859-1
Byte Width: 1–1 bytes
Introduced: 1987

Latin-1 (ISO-8859-1) Character Set (256 characters)

All characters supported by Latin-1 (ISO-8859-1), with their UTF-8 bytes for comparison. Characters not in the table are supported by Unicode but not Latin-1 (ISO-8859-1).
