ISO-8859-8-I is the IANA charset name for the character encoding ISO/IEC 8859-8 used together with the control codes from ISO/IEC 6429 for the C0 (00–1F hex) and C1 (80–9F) parts. The characters are in logical order.

Escape sequences (from ISO/IEC 6429 or ISO/IEC 2022) are not to be interpreted. Most applications only interpret the control codes for LF, CR, and HT. A few applications also interpret VT, FF, and NEL (in C1). Very few applications interpret the other C0 and C1 control codes.

ISO-8859-8 is sometimes in logical order (HTML, XML), and sometimes in visual (left-to-right) order (plain text without any markup).

Logical order for this charset requires bidi processing for display.


8I or 8-I can refer to:

8i (virtual reality), a New Zealand-based virtual reality company established in 2014

IATA code for MyAir

PowerXCell 8i, IBM model of Cell (microprocessor)

747-8i, a model of Boeing 747



ISO/IEC 8859-8

ISO-8859-8ISO/IEC 8859-8, Information technology — 8-bit single-byte coded graphic character sets — Part 8: Latin/Hebrew alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings. ISO/IEC 8859-8:1999 from 1999 represents its second and current revision, preceded by the first edition ISO/IEC 8859-8:1988 in 1988. It is informally referred to as Latin/Hebrew. ISO/IEC 8859-8 covers all the Hebrew letters, but no Hebrew vowel signs. IBM assigned code page 916 to it.ISO-8859-8 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. The text is (usually) in logical order, so bidi processing is required for display. Nominally ISO-8859-8 (code page 28598) is for “visual order”, and ISO-8859-8-I (code page 38598) is for logical order. But usually in practice, and required for HTML and XML documents, ISO-8859-8 also stands for logical order text. There is also ISO-8859-8-E which supposedly requires directionality to be explicitly specified with special control characters; this latter variant is in practice unused.

This character set was also adopted by Israeli Standard SI1311:2002. Over a decade after the publication of that standard, Unicode is preferred, at least for the Internet (meaning UTF-8, the dominant encoding for web pages). ISO-8859-8 is used by less that 0.1% of websites.


Windows-1255 is a code page used under Microsoft Windows to write Hebrew. It is an almost compatible superset of ISO 8859-8 – most of the symbols are in the same positions (except for A4, which is 'sheqel sign' in Windows-1255 but 'generic currency sign' in ISO 8859-8 and except for DF, which is undefined in Windows-1255 but 'double low line' in ISO 8859-8), but Windows-1255 adds vowel-points and other signs in lower positions.

Modern applications prefer Unicode to Windows-1255, especially on the Internet; meaning UTF-8, the dominant encoding for web pages (or UTF-16, while not on the Internet for security reasons). Windows-1255 is used by less that 0.1% of websites.
