Support non-Unicode locales

[NoraCodes]

Hi! I am currently trying to run Toot on my Digital Equipment Corporation VT420, which doesn't support Unicode. The best I've got is ISO Latin-1. However, toot currently doesn't work at all in this locale:

nora@racketmousse:~$ LC_ALL=en_US.iso88591 toot tui

UnicodeEncodeError: 'latin-1' codec can't encode characters in position 0-4: ordinal not in range(256)

Similar errors occur with toot timeline. Would it be possible to get at least basic functionality without fancy Unicode characters?

Thanks!

P.S. here's what happens if you feed the Unicode characters into the VT. It's not particularly lovely.

Not bad - further than I got while attempting login UnicodeEncodeError: 'latin-1' codec can't encode character '\u2713' in position 5: ordinal not in range(256) :-)

@NoraCodes Firstly, I love your use case. :) Currently the whole project assumes utf-8. Making it support latin1 would be possible, but might require some re-jigging. Probably won't be high on my list of priorities for the near future, sorry.
