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 in strings where spaces are not permitted to create visual spacing, 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.
