I have a table that I'm drawing using diagonal lines in ascii. Basically a mix of /\^V<>, like this:
^
/ \
< >
\ /
v
I would prefer to write this using unicode characters more fit for the job, like ╱, ╳ and ╲, but I lack characters for ^, V, < and >, so I can only do this:
╳
╱ ╲
╳ ╳
╲ ╱
╳
Which turns out to be insufficient for what I'm trying to convey.
I wonder if there are some box-drawing characters I'm missing?
I'm basically going by this block, and it might be that another block has something more suitable for drawing diagonals.
I also checked out http://shapecatcher.com/, and it suggests using e.g. a capital Lambda, Λ, for ^, but things still don't quite match up.
If there are currently no such characters, do you know if there are any plans for adding them, or can you think of another nice way to display such a table in the terminal?
I hope this isn't too much of a necropost. I also want to know.
Ok, I'm going to hyperfocus on this. I'm going to give you every possible option I can find. Since this is a asthetic matter, you have to choose for yourself based on the project and its needs. I draw my own conclusion based on similarity to a turned square, which I assume is the goal here.
And it turns out, no, you're not really missing a special character space that has all the answers. I wish.
Firstly, it seems like you're specifically intent on using only 1 char per angle in your diamonds. This is going to artificially limit your options.
The usual whitespace interior of a 2 char diamond vs a 1 char diamond:
/\ ^
/░░\ /░\
/░hi░\ can't center text <░!░> can center text
\░hi░/ \░/
\░░/ v
\/
If the above diagram doesn't matter for your project, then please consider using a 2 char diamond as they are much easier to construct.
2 chars per angle (if centering isn't a hurdle for you): The headings are the names of the unicode blocks that these characters come from.

That's right, the day is saved by Dingbats and the IPA. Honestly, isn't it always?
