`Ubuntu Mono` font doesn't show the arrow for bash theme.

[Larry Wei]

`Ubuntu Mono` font doesn't show the arrow for bash theme:
I installed oh-my-bash from https://github.com/ohmybash/oh-my-bash, and set the terminal font to 'Ubuntu Mono' for my flavor, but it doesn't show the right arrow of 'agnoster' theme.
Hope it could been fixed soon.
