I need a font that has all the special characters such as Ω and Ψ. I also need the font to have no spaces when making these characters:

  ┌─┐
  │ │
  └─┘

And is aligned. As shown here, the box has spaces in between, making it imperfect for menu in my program I’m currently making. I tried all default fonts pre-installed in my computer but they failed 1 of the three scenarios.

Also, I’m not exactly sure if I should make my own font using programs because I do not know of the subject.
