    The way it was explained to me was that with UTF-8 and company, you only
    have to maintain state for a short, fixed number of bytes, whereas with
    something like ISO 2022 or SCSU you have to maintain state for an
    arbitrary amount of data, possibly gigabytes.

    While I haven't bought into every piece of Unicode received wisdom I've
    heard, this definition of "stateless" makes perfect sense to me and I no
    longer think of UTF-(8n) as stateful.
