U+204F Reversed Semicolon

U+204F was added in Unicode version 3.2 in 2002. It belongs to the block U+2000 to U+206F General Punctuation in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Punctuation and is commonly used, that is, in no specific script. It is also used in the scripts Adlam, Arabic.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+204F forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

The semicolon ; (or semi-colon) is a symbol commonly used as orthographic punctuation. In the English language, a semicolon is most commonly used to link (in a single sentence) two independent clauses that are closely related in thought, such as when restating the preceding idea with a different expression. When a semicolon joins two or more ideas in one sentence, those ideas are then given equal rank. Semicolons can also be used in place of commas to separate items in a list, particularly when the elements of the list themselves have embedded commas.
The semicolon is one of the least understood of the standard marks, and is not frequently used by many English speakers.
In the QWERTY keyboard layout, the semicolon resides in the unshifted homerow beneath the little finger of the right hand and has become widely used in programming languages as a statement separator or terminator.
