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 ...
This enables text-processing systems for scripts that do not use explicit spacing to recognize where word boundaries are for the purpose of handling line breaks appropriately. The zero-width space is Unicode character U+200B , and is located in the Unicode General Punctuation block.
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 ...
Braille ASCII (or more formally The North American Braille ASCII Code, also known as SimBraille) is a subset of the ASCII character set which uses 64 of the printable ASCII characters to represent all possible dot combinations in six-dot braille.

In Indic scripts, insertion of a ZWNJ after a consonant either with a halant or before a dependent vowel prevents the characters from being joined properly: [4] In Devanagari, the characters क् and ष typically combine to form क्ष, but when a ZWNJ is inserted between them, क्ष (code: क्‌ष) is seen instead.
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
Compatibility characters are those included for support of legacy text handling systems that do not make a distinction between character and glyph the way Unicode does. For example, many Arabic letters are represented by a different glyph when the letter appears at the end of a word than when the letter appears at the beginning of a word.
