Vim has digraphs for all of these characters, which I like to use. e.g. you can get ┌ with <C-K>dr (d = down, r = right), and ┨ with <C-K>Vl (V = heavy vertical, l = left). To find the mappings, :digraphs shows the whole list, or copy this block of text and put the cursor over any of the characters in normal mode and type ga and it’ll echo things like “<┠> 9504, Hex 2520, Oct 22440, Digr Vr”.

(I use a Compose key for almost all character composition, with plenty of custom mappings in my ~/.XCompose, but box drawing specifically I have skipped and use Vim digraphs, and so drop into Vim any time I want to write any.)

I know, I've used them in the past. However, I get annoyed by having to remember the exact sequence for the character I want. And often, when drawing a line, I'll just copy some characters that are already there anyway.

Also, I tend to jump a lot between editors/IDEs nowadays so I prefer workflows that don't depend on a specific tool.
