    First of all, you don’t want a fixed-width space in this particular
    case, just a non-breaking one (ask the typesetters).

    A fixed-width space is desirable in cases like:

    “As he was setting the ion gun in place, his fingers had slipped
    through the portal—ordinarily no problem, but this morning his hip
    had also brushed the toggle switch on the control panel at the left
    of the portal.”

    You’d type “portal,ZWNBSP,THIN SP,ZWNBSP,EM DASH,THIN SP,ordinarily”.
