LZ4 isn't a fantastic compression algorithm from a compression ratio standpoint. What it makes up for is that a decoder is extremely easy to write and is very small and fast. This makes it good for embedded applications and retro computers. The COM2EMOJI will operate in three stages: first, the 17 byte emoji decoder will be emitted via raw emoji code. then a roughly 60 byte (currenly) LZ4 decoder will be unpacked into memory using the inefficient but simple 8-bit-per-grapheme packing. The LZ4 decoder will then be able to extract 10 bits per grapheme from the payload emoji.
