A more efficient way of encoding binary data as strings in localStorage

I think I've found a more efficient way of encoding binary data as strings, with 0% overhead (this might have been brought up before):
Iterate over every byte of the binary data and append String.fromCharCode(byte) to the output string. The resulting string can be stored in localStorage, and when reversed (with .charCodeAt) returns the original binary data fully intact (from 0-255).
