U+2068 First Strong Isolate
U+2068 was added in Unicode version 6.3 in 2013. It belongs to the block General Punctuation in the Basic Multilingual Plane.
This character is a Format and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it sets the direction of the following text snippet based on its first character. When changing direction it is not mirrored. U+2068 prohibits a line break before it.
The Wikipedia has the following information about this codepoint:
A bidirectional text contains two text directionalities, right-to-left (RTL) and left-to-right (LTR). It generally involves text containing different types of alphabets, but may also refer to boustrophedon, which is changing text direction in each row.
An example is the RTL Hebrew name Sarah: שרה, spelled sin (ש) on the right, resh (ר) in the middle, and heh (ה) on the left. Many computer program failed to display this correctly, because they were designed to display text in one direction only.
Some so-called right-to-left scripts such as the Persian script and Arabic are mostly, but not exclusively, right-to-left—mathematical expressions, numeric dates and numbers bearing units are embedded from left to right. That also happens if text from a left-to-right language such as English is embedded in them; or vice versa, if Arabic is embedded in a left-to-right script such as English.
