U+2066 "⁦" Left-to-Right Isolate Unicode Character

Unicode Version 17.0

U+2066 "⁦" Left-to-Right Isolate is an invisible formatting character used in the bidirectional text algorithm to treat the enclosed sequence of characters as a single, left-to-right directional unit, isolated from the surrounding text's directionality. It is part of the Unicode Bidirectional Isolate characters, designed to handle complex mixed-script text, such as Arabic or Hebrew fragments within English prose, without affecting the overall layout. Unlike legacy directional overrides, this isolate method prevents the enclosed text from influencing adjacent characters, making it a clean way to embed a left-to-right run in a right-to-left context or vice versa. Its primary purpose is to ensure correct display in applications like multilingual websites or text editors, where proper rendering of directional cues is essential for readability.
