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

Probably macOS specific: that character displays fine on MS-Windows.

On my GNU/Linux box with both GTK and Lucid builds, I see that the
blanked dots do show up, similar to what the OP shows in their linked
screenshot. Interestingly, I *don't* see the blanked dots in the
completion window for C-x 8 RET braille TAB.

Doing C-u C-x = on the character in the completion window shows (where
it's blanked out as expected)
xft:-unknown-DejaVu Serif-normal-italic-normal-*-15-*-*-*-*-0-iso10646-1 (#xA6F)
whereas, the same character in other places shows (where it's not
entirely blanked out)
xft:-unknown-Unifont-normal-normal-normal-*-15-*-*-*-d-0-iso10646-1 (#x2803)

Indeed, with Unifont I see it here also. I found one or two other

So if a different font works for the OP as well, I think we can
conclude that this is a font issue, not an Emacs bug.

Thanks, so I'm closing the bug.
