Perl has a built-in function for A-Za-z_0-9: quotemeta()

Nearly there. Too bad, Anonymous Monk cannot fix his own typos. Correctly said and taken from perldoc -f quotemeta:


Returns the value of EXPR with all the ASCII non-"word" characters backslashed. (That is, all ASCII characters not matching "/[A-Za-z_0-9]/" will be preceded by a backslash in the returned string, regardless of any locale settings.) This is the internal function implementing the "\Q" escape in double-quoted strings. (See below for the behavior on non- ASCII code points.)
