Encoding scheme to encode any Unicode string with only [0-9a-zA-Z_]

Double-X-Encoding is an encoding scheme to encode any Unicode string with only characters from [0-9a-zA-Z_]. Therefore it's quite similar to URL percent-encoding. It's especially useful for GraphQL ID generation, as it includes support for encoding leading digits and double underscores.
