I'm writing an UTF-8 decoder (just for fun) and there's quite a lot of information to understand even before starting that. And as I started I found that it naturally codes itself into a state machine with 12 byte types, 8 decoding states and 11 moves. If I rewrite my notes to condense them I expect to get maybe 4 screenfuls of comments :) Not complex but not something easily digestible by a completely green junior member perhaps.
