A1Z26 cipher

A1Z26 is very simple direct substitution cypher, where each alphabet letter is replaced by its number in the alphabet.

Below is the A1Z26 encoder/decoder. Here all letters are set to lowercase, the English alphabet is used, and all non-alphabet symbols are not transformed. In decoding, all numbers (from 1 to 26) should be separated by any non-digit symbol (dash, space).
