    ROT47

A ROT47 encrypter/decrypter implementation in 103 bytes.
"ROT47 is a derivative of ROT13 which, in addition to scrambling the basic letters, also treats numbers and common symbols. Instead of using the sequence A–Z as the alphabet, ROT47 uses a larger set of characters from the common character encoding known as ASCII. Specifically, the 7-bit printable characters, excluding space, from decimal 33 '!' through 126 '~', 94 in total, taken in the order of the numerical values of their ASCII codes, are rotated by 47 positions, without special consideration of case."

        String.fromCharCode((a=a.charCodeAt()+47, a > 126 ? a - 94 : a))    // Rotate character index by adding 47. If the result is > 126 (the max) loop to the beginning by subtracting 94
