There might be some misunderstanding: using setq-local makes the
character local to a buffer, whereas I thought you wanted to use a
special character only for the lines that exceed the fill-column?
When I use your code, then whenever I'm on a line that is too long,
_all_ the fill-column indicators in the window change into the U+2503
character shown in red, not just the indicator of that single line.

Did I misunderstand what you are trying to accomplish?
