The input string containing the text to convert.

Return Value

A string of characters with any escaped characters converted to their unescaped form.

Exception typeCondition


str is a null reference (Nothing in Visual Basic).

As an example, Unescape replaces \x61 with a and \n with a new-line character (ASCII 10). Unescape reverses the transformation done by Escape. (Of course, Escape cannot perfectly reverse Unescape because it cannot deduce from an unescaped string which characters may have been previously escaped.)
