You should also be aware that many chatters are apparently using clients rigged to get around the “duplicate message” spam restrictions in Twitch. See: https://github.com/pajbot/tmi-rate-limits – essentially they append a space character followed by the reserved Unicode character U+E0000 to the end of their message to get around the Twitch filter. As a byte string you’ll see this as %F3%A0%80%80 which I see you noticed.
