What's wrong with 1024?  If that might be too few, enlarge it.

I hope by "do the same thing" you do NOT mean to have 1024 characters
as the border, but rather replace "|" with some non-ASCII character.

It hides in one of the extra slots of the display table.  See the node
"Display Tables" in the ELisp manual.

> CAN I set that?

Yes, something like

  (set-display-table-slot (setq standard-display-table (make-display-table))
                          'vertical-border ?│)

But beware: the character you use must be encodable by your
terminal-coding-system, otherwise you will get a question mark "?"
instead of your fancy character.

(Personally, I question the utility of doing what you want, but that's
me.)
