The backslash (\) is a typographical mark used mainly in computing and is the mirror image of the common slash (/). It is sometimes called a hack, whack, escape (from C/UNIX), reverse slash, slosh, downwhack, backslant, backwhack, bash, reverse slant, and reversed virgule.[1][2] In Unicode and ASCII it is encoded at U+005C \ REVERSE SOLIDUS (92decimal).
