U+2060 Word Joiner

U+2060 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 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 acts as Boundary Neutral. When changing direction it is not mirrored. U+2060 prohibits a line break around it.

The Wikipedia has the following information about this codepoint:

The word joiner (WJ) is a Unicode format character which is used to indicate that line breaking should not occur at its position. It does not affect the formation of ligatures or cursive joining and is ignored for the purpose of text segmentation. It is encoded since Unicode version 3.2 (released in 2002) as U+2060 WORD JOINER (&NoBreak;).
The word joiner replaces the zero-width no-break space (ZWNBSP, U+FEFF), as a usage of the no-break space of zero width. The ZWNBSP is originally and currently used as the byte order mark (BOM) at the start of a file. However, if encountered elsewhere, it should, according to Unicode, be treated as a word joiner, a no-break space of zero width.
The deliberate use of U+FEFF for this purpose is deprecated as of Unicode 3.2, with the word joiner strongly preferred.
