It's not obvious to me why the latin1 encoding is in this list as its just one
of all the 8-bit char sets.
Why is it needed?
The Latin-1 (ISO 8859-1) charset is kind of special: it maps bytes
0x00-0xFF to Unicode characters U+0000-U+00FF and decoding from latin1
cannot fail.
This apparently makes it useful for not-quite-text, not-quite-bytes
protocols like HTTP. In particular, WSGI (PEP 3333) uses latin-1 for
headers.
It was commonly used as the locale encoding in Europe 10 years ago,
but nowadays most Linux distributions use UTF-8 as the locale
encoding.
I'm also fine with restricting the list to 3 encodings: ASCII, UTF-8
and Windows ANSI code page.
