The left-to-right mark (LRM) is a control character (an invisible formatting character) used in computerized typesetting of text containing a mix of left-to-right scripts (such as Latin and Cyrillic) and right-to-left scripts (such as Arabic, Syriac, and Hebrew). It is used to set the way adjacent characters are grouped with respect to text ...
Bidirectional script support is the capability of a computer system to correctly display bidirectional text. The term is often shortened to "BiDi" or "bidi".Early computer installations were designed only to support a single writing system, typically for left-to-right scripts based on the Latin alphabet only.
The right-to-left mark (RLM) is a non-printing character used in the computerized typesetting of bi-directional text containing a mix of left-to-right scripts (such as Latin and Cyrillic) and right-to-left scripts (such as Arabic, Persian, Syriac, and Hebrew). RLM is used to change the way adjacent characters are grouped with respect to text ...
Similarly, Unicode handles the mixture of left-to-right-text alongside right-to-left text without any special characters. For example, one can quote Arabic (“بسم الله”) (translated into English as "Bismillah") right alongside English and the Arabic letters will flow from right-to-left and the Latin letters left-to-right.
The Unicode Standard assigns various properties to each Unicode character and code point. [1] [2]The properties can be used to handle characters (code points) in processes, like in line-breaking, script direction right-to-left or applying controls.

Writing direction (right-to-left, left-to-right, or boustrophedon) varies based on the language and even the time period. For simplicity most scholars use left-to-right and this is the Unicode default direction for the Old Italic block. For this reason, the glyphs in the code chart are shown with left-to-right orientation. [20]
