Yup:

  (setq header-line-format
        (concat (propertize "|" 'display '(space :width 1)) "hello world"))

That makes the first character of the header-line exactly one `default'
character wide -- even if the header-line is displayed in a different
font....

You can use a floating-point number (> 0 < 1) instead of `1' to make it
smaller, but annoyingly there's no way to specify exact pixel widths
(which is what I gather would be needed to work well with fringes).
