Converts a String to a double-quoted format. The String itself is enclosed in double quotes ", and double quotes themselves are escaped using backslash \. The characters \b, \t, \n, \f, \r, and \ (corresponding to backspace, tab, linefeed, formfeed, carriage return, and backslash) are written using their canonical escape sequences. Any other character <= 0x1f or >= 0x7f is written by a backslashed octal number.

Parameters:

s - String to be converted to quoted format
