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.
But usually in practice, and required for XML documents,[citation needed] ISO-8859-8 also stands for logical order text.
[5] 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.
It adds support for vowel 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] (meaning UTF-8, the dominant encoding for web pages).
