ISO/IEC 8859-8,Information technology — 8-bit single-byte coded graphic character sets — Part 8: Latin/Hebrew alphabet, is part of theISO/IEC 8859 series of ASCII-based standardcharacter encodings.ISO/IEC 8859-8:1999 from 1999 represents its second and current revision, preceded by the first editionISO/IEC 8859-8:1988 in 1988. It is informally referred to asLatin/Hebrew.ISO/IEC 8859-8 covers all theHebrew letters, but noHebrew vowel signs. IBM assignedcode page 916 (CCSIDs 916 and 5012) to it.^[2][3][4] This character set was also adopted byIsraeli Standard SI1311:2002, with some extensions.

ISO-8859-8 is theIANA preferred charset name for this standard when supplemented with theC0 and C1 control codes fromISO/IEC 6429. The text is (usually) in logical order, sobidi processing is required for display. NominallyISO-8859-8 (code page 28598) is for “visual order”, andISO-8859-8-I (code page 38598) is for logical order. But usually in practice, and required for XML documents,^{[citation needed]}ISO-8859-8 also stands for logical order text. TheWHATWG Encoding Standard used byHTML5 treats ISO-8859-8 andISO-8859-8-I as distinct encodings with the same mapping due to influence on the layout direction, but notes that this no longer applies toISO-8859-6 (Arabic), only to ISO-8859-8.^[5]

There is alsoISO-8859-8-E which supposedly requires directionality to be explicitly specified with special control characters; this latter variant is in practice unused.

TheMicrosoft Windows code page for Hebrew,Windows-1255, is mostly an extension of ISO/IEC 8859-8 without C1 controls, except for the omission of the double underscore, and replacement of the generic currency sign (¤) with thesheqel sign (₪). It adds support forvowel points as combining characters, and some additional punctuation.

Over a decade after the publication of that standard,Unicode is preferred, at least for the Internet^[6] (meaningUTF-8, the dominant encoding for web pages). ISO-8859-8 is used by less than 0.1% of websites.^[7]

FD is left-to-right mark (U+200E) and FE is right-to-left mark (U+200F), as specified in a newer amendment as ISO/IEC 8859-8:1999.

Israeli Standard SI1311:2002 matches ISO/IEC 8859-8:1999 except for a number of additional character allocations for theeuro sign,new shekel sign and more advancedexplicit bidirectional formatting.^[12]
