I can confirm that both Chromium and Tor Browser appear to misrender the
box drawing characters on an Android-derived (https://calyxos.org/)
device I got a chance to look at.

This is presumably a font rendering issue, probably something comparable
to https://bugs.debian.org/981577, which i just reported on Debian.

I've reported the issue to CalyxOS as well:
https://gitlab.com/CalyxOS/calyxos/-/issues/334

If this is a problem for you on a platform that you care about, please
report it to them.  Feel free to use
https://dkg.fifthhorseman.net/table.txt as a reference for any bug
report -- i'll leave it up.

In the meantime, though, we shouldn't avoid using standard, well-defined
characters just because some font rendering paths screw them up.  those
are bugs that should be fixed in the appropriate places.
