bug#33207: 26.1; Incorrect display of braille unicode

[Justin Heyes-Jones]

Hi, I'm not sure if this is a bug or if there is some setting related to the display of unicode that I don't know about. 

The problem is that the braille unicode character BRAILLE PATTERN BLANK (0x2800) doesn't display as blank but appears as what looks like a different character. I have submitted a question to stackoverflow which includes screen shots of what the code should look like in both terminal and in emacs. I am running on macOS Mojave 10.14.

https://stackoverflow.com/questions/53024626/why-is-emacs-displaying-unicode-character-braille-pattern-blank-as-a-non-blank-c

Thanks!

Justin
