U+2017 Double Low Line

U+2017 was added in Unicode version 1.1 in 1993. 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.

The glyph is a compatibility composition of the glyphs Glyph for U+0020 Space, Glyph for U+0333 Combining Double Low Line. 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+2017 forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

An underscore or underline is a line drawn under a segment of text. In proofreading, underscoring is a convention that says "set this text in italic type", traditionally used on manuscript or typescript as an instruction to the printer. Its use to add emphasis in modern finished documents is generally avoided.

The (freestanding) underscore character, _, also called a low line, or low dash, originally appeared on the typewriter so that underscores could be typed. To produce an underscored word, the word was typed, the typewriter carriage was moved back to the beginning of the word, and the word was overtyped with the underscore character.

In modern usage, underscoring is achieved with a markup language, with the Unicode combining low line or as a standard facility of word processing software. The free-standing underscore character is used to indicate word boundaries in situations where spaces are not allowed, such as in computer filenames, email addresses, and in Internet URLs, for example Mr_John_Smith. It is also used as a proofreader's mark, to indicate that text should be underscored or italicised when typeset, for instance _thus_ is to be rendered as thus or thus.
