How do I make byobu start with unicode support by default? If I have done
byobu-enable how I can set this
Since you're asking about
-u and not
-U, I assume you're asking about Byobu's tmux backend...
In this case, you can add any additional tmux configuration options to a local tmux configuration at
~/.byobu/.tmux.conf. In there, you should add the following:
set-window-option -g utf8 on set-option -g status-utf8 on
Full disclosure: I'm the author and maintainer of Byobu.
This might depend on how you start byobu. If you start it from the launcher like I do then you can follow the instructions in this answer to add the "-u" parameter to it: Specify parameters for launcher program .
Note: Dustin's answer, unfortunately, did not work for me for whatever reason. If I started a non-byobu terminal it had utf8 setup correctly and if I used tmux the characters showed up, but not with byobu's terminal.
Edit: To those who edited my answer to change the lowercase 'u' to a capital 'U' that is incorrect. A capital 'U' is not a valid parameter to input when starting byobu. Here's the text in my launcher icon: "env TERM=xterm-256color byobu -u". If you run byobu -u from a new terminal (not from byobu) it works, but if you run byobu -U it spits out a clear message that capital 'U' is not a valid parameter:
usage: tmux [-2lquvV] [-c shell-command] [-f file] [-L socket-name] [-S socket-path] [command [flags]]
