Pattern Element Escaping

'\c' means the engine should not use 'c' as pattern item, i.e. pass it to the output stream without processing.
Sample symbols those should be escaped: A, a, N, X, @, $, <, >, (, ), #, [, ].

Examples

'\Number' pattern produces "Number" string when 'Number' generates "1umber" or something like.
