Because UTF-8 is constructed so that it allows character boundary detection,
it is extremely regular and therefore easy to detect. The same applies for
ISO 2022 with C1 controls; before you can use SS2 or SS3, you have to
declare what you want in G2 or G3. Automatic detection needs a little bit
of code, but is not too difficult.
