The basics of Bidi

Deborah (Debbie) Anderson (Project lead, Script Encoding Initiative, Dept. of Linguistics, UC Berkeley) is helping in the organisation of a Unicode-hosted event on bidirectional text.

“The basics of Bidi”

Tuesday, June 25, 2024 at 08:00 AM Pacific Time.


A number of scripts, such as Arabic and Hebrew, write their letters horizontally on a page or screen, running right to left. A complication for these scripts is that other characters, such as digits, flow left-to-right, and can occur on the same line, or even alongside other left-to-right text, such as Latin. Text that handles both right-to-left and left-to-right text is called “bidirectional” text (“bidi” in short). How to handle bidi text on browsers and in other software is challenging for both general users and implementers. This webinar will describe the basics with examples. It will be followed by a live question-and-answer period. 

This is part 1 of a 2-part series, with the second more in-depth session to take place August 13, 2024. Note: This webinar will be recorded and it will be available for viewing later on the Unicode Consortium YouTube channel.
