I've seen snippets like this:

(set-display-table-slot standard-display-table 'vertical-border (make-glyph-code ?┃))

That claim to make emacs use a prettier window divider character. However, standard-display-table is nil in a emacs24.4 -Q. How can I fix this?

The docs of standard-display-table refer to buffer-display-table which mentions that you can create display tables with make-display-table if necessary.

This means the following should work:

(let ((display-table (or standard-display-table (make-display-table))))
  (set-display-table-slot display-table 'vertical-border (make-glyph-code ?┃))
  (setq standard-display-table display-table))
  • Thanks. I though something like this existed, I just couldn't find it. – PythonNut Jan 10 '15 at 18:38

You do not need to fiddle with a display table. Just customize face window-divider: M-x customize-face window-divider.

I use a Blue foreground attribute, for example. Here is a screenshot, with scroll bars turned off:

Oops. I see now that you are interested in TTY, not graphics. In that case, you can try customizing face vertical-border, giving it, for example, a width attribute value of narrow. Here is a screenshot of that:
