Rendering braille characters without the empty dots

[joshka]

Describe the bug My terminal (iterm2) renders braille characters without the empty dots in the various fonts I have installed, but try as I might I can't seem to get vhs to render them the same:

Hey thanks for this issue! I have added a fallback for "Apple Symbols" which appears to me to fix this issue on macs. I will add the Linux fix shortly as well.

Thanks! This should make rendering screencasts of ratatui just that little bit easier.

at least for me on vhs 0.6.0 and Linux (Manjaro 23.0.0) and KDE Konsole, it renders braille correctly:
