ISO-8859-8-I

In today's world, ISO-8859-8-I continues to be a topic of great relevance and interest to a large sector of the population. Over time, ISO-8859-8-I has managed to remain at the center of attention of academics, professionals and amateurs, demonstrating its importance and impact in different areas of society. Throughout history, ISO-8859-8-I has been the subject of numerous studies, debates and reflections, which has contributed to enriching knowledge on this topic. In this article, we will explore some key aspects related to ISO-8859-8-I, with the aim of delving into its meaning, its evolution and its relevance today.

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). The WHATWG Encoding Standard used by HTML5 treats ISO-8859-8 and ISO-8859-8-I as distinct encodings with the same mapping due to influence on the layout direction, but notes that this no longer applies to ISO-8859-6 (Arabic), only to ISO-8859-8.

Logical order for this charset requires bidi processing for display.

The Microsoft Windows code page for Hebrew, Windows-1255, uses logical order, and adds support for vowel points as combining characters, and some additional punctuation. It is mostly an extension of ISO-8859-8-I without C1 controls, except for the omission of the double underscore, and replacement of the universal currency sign (¤) with the sheqel sign (₪).

Note: ISO-8859-8 and ISO-8859-8-I are distinct encoding names, because ISO-8859-8 has influence on the layout direction. And although historically this might have been the case for ISO-8859-6 and "ISO-8859-6-I" as well, that is no longer true.
