Some characters are not rendered at small font sizes

[boltronics]

Windows Terminal version (or Windows build number)

1.10.2383.0

Other Software

tree v1.8.0 (inside a Debian WSL2 environment)

Steps to reproduce

Set the Font size to 8, and Font face to something like Consolas, or Liberation Mono.

Alternatively, set Font size to 9 and set Font face to Terminus (TTF) For Windows (my personal preference).

Run tree

(or run pass or any other software that relies on it).

Expected Behavior

You should see something like:

~$ tree dir
dir/
├── file1.txt
└── file2.txt

Actual Behavior

Instead, you'll see something like:

~$ tree dir
dir/
    file1.txt
    file2.txt

It took me a lot of testing to figure out that I needed to bump my font size up for these characters to render, since every font I tried wouldn't show it (although that was apparently just luck since some fonts do render the lines with varying degrees of success). I initially thought the colour was somehow matching the background, since the characters were present since I could copy them. Unfortunately, I find that increasing the font size to the required degree is not acceptable.

A more acceptable work-around is to define a shell function like so:

~$ tree() { TREE_CHARSET='C' /usr/bin/tree "${@}" ; }
~$ tree testdir/
testdir/
|-- file1.txt
`-- file2.txt

0 directories, 1 file
~$

Of course it still looks more ugly than it should, but at least it shows something without affecting everything else.

If I apt install terminator and the Terminus fonts and run it under VcXsrv, it works perfectly.

@boltronics "tree -A" turns on ANSI line graphics hack. Works every time!

[boltronics]

@elsaco Thanks for the suggestion. Unfortunately that made no difference for me. Also, when pressing Ctrl+C because I accidentally ran tree -A across a large directory, I got the corruption you see in the top pane. I've never seen that happen before (although that'll be unrelated).

[boltronics]

FWIW, corruption was fixed with echo ^N (that's ctrl+v, ctrl+n) although I could have just reopened a new window I guess.

I think this is probably covered by #7927 or #5897 (see for example https://github.com/microsoft/terminal/issues/5897#issuecomment-803492674). Possibly also #6161.

Thanks @j4james you are right, it's a dupe of #7927 I'd say. Closing.
