Add figures for box lines

[ehmicky]

What are your thoughts on adding figures for box lines?

They display well on all environments. The following screenshots shows them both as individual characters, and displayed on several rows/columns.

Ubuntu 20.10, Gnome terminal:

Windows 10, cmd.exe (CP850):

I checked on macOS default terminal, and it looks good too 👍

I believe all of the above are useful, but offering a subset is also an option. The high number of characters is mostly due to different variants of dashes and boldness.

At the moment, the only related figure in this library is line (U-2500) (not included above).

👍 To the person that ends up submitting a PR for this, good luck naming all of these.

I think we can use system of prefixes and suffixes (although I agree the names will most likely be verbose).

Proposal for naming:

• line, e.g. ━
• lineVertical, e.g. ┃
• lineDownRight, lineDownLeft, lineUpRight or lineUpLeft, e.g. ┏ ┓ ┗ ┛
• lineUpDownRight, lineUpDownLeft, lineDownLeftRight or lineUpLeftRight, e.g. ┣ ┫ ┳ ┻
• lineUpDownLeftRight, e.g. ╋
• lineCross for ╳
• lineBackslash for ╲
• lineSlash for ╱

This can be followed by "variants":

• nothing/empty, e.g. │
• Bold, e.g. ┃
• Double, e.g. ║
• Dashed0, Dashed1, ..., Dashed15 for all dashed variants, e.g. ┇

When a symbol combines several variants, they are appended to each part of it. For example, lineUpBoldDownLeftBoldRight for ╃

I would also suggest leaving out ‾ (U-203e) as it is not centered and not really meant as a box line.

What do you think?

[sindresorhus]

That sounds good to me.
