However, this is automatically set up in your .bashrc and .zshrc if you use the
bundled [install](https://github.com/junegunn/fzf/blob/master/install) script.
### Incorrect display on Ruby 1.8
### Rendering issues
It is reported that the output of fzf can become unreadable on some terminals
when it's running on Ruby 1.8. If you experience the problem, upgrade your Ruby
to 1.9 or above. Ruby 1.9 or above is also required for displaying Unicode
characters.
If you have any rendering issues, check the followings:
1. Make sure `$TERM` is correctly set. fzf will use 256-color only if it
contains `256` (e.g. `xterm-256color`)
2. If you're on screen or tmux, $TERM should be either `screen` or
`screen-256color`
3. Some terminal emulators (e.g. mintty) have problem displaying default
background color and make some text unable to read. In that case, try `--black`
option. And if it solves your problem, I recommend including it in
`FZF_DEFAULT_OPTS` for further convenience.
4. If you still have problem, try `--no-256` option or even `--no-color`.
5. Ruby 1.9 or above is required for correctly displaying unicode characters.
