The Wikipedia has the following information about this codepoint:

A bar or stroke is a modification consisting of a line drawn through a grapheme. It may be used as a diacritic to derive new letters from old ones, or simply as an addition to make a grapheme more distinct from others. It can take the form of a vertical bar, slash, or crossbar.

A stroke is sometimes drawn through the numbers 7 and 0, to make them more distinguishable.

In phonetic transcription, a stroke through a letter often indicates that the sound is a fricative.

For the specific usages of various letters with bars and strokes, see their individual articles.
