New 'big5bbs' encoding!
Sometimes called "BBS 半形字" (half-width characters), and the
PCMan/PttBBS terminal clients handle it with a custom font that maps
those lone high bytes to specific glyphs. It's very popular within
Taiwanese BBS culture but has no formal name or IANA-registered codec.
It's essentially Big5 + a proprietary single-byte overlay for art
characters.
Add --always-dont and --always-wont=TEL,OPTS
This mirrors --always-do and --always-will. If you're making custom
clients and servers or automation's you might find issues or bugs in our
implementation or the remote's, common ones like TTYPE, NAWS etc, that
can be worked around by rejecting them entirely.
