Support for unicode codes

[Pk13055]

Currently if you replace a given symbol with its unicode code value (and not the actual symbol itself), it ends up printing the code itself.

Here is the relevant tmux config part (for reference)

# root indicator
tmux_conf_theme_root='\uf21b'
tmux_conf_theme_root_fg='none'
tmux_conf_theme_root_bg='none'
tmux_conf_theme_root_attr='bold,blink'

The content of the tmux_conf_theme_ variables are given to tmux mostly unchanged which you can see if you do tmux show -gv status-left or tmux show -gv status-right.

tmux doesn't interpret \uf21b, you have to give it UTF-8

How would one work towards interpreting this the right way? Given how useful oh-my-tmux has been for me, I would love to add this. This would serve as a great way for us to add extra symbols (stuff under Nerd Fonts, etc) without having to UTF-8 everything manually. There's a quick fix I can think of. Before passing the config to tmux directly, we could:

echo config > .temp_config
mv .temp_config config
# pass this config (having made the terminal do all the translation for us :D) to tmux

Hey @Pk13055 👋

Do you mind giving the gh-148 branch a try?
