    Could you explain that in a little more detail, please?

    I take what you said to mean that
       - U+FE45 and U+FE46 have their own glyphs
       - these glyphs are intended to be scaled down to 50% of the text size
       - therefore in the font they are approximately twice the size of the
         comma rather than approximately the same size
       - therefore an application wishing to use U+FE45 as an emphasis mark
         should scale its glyph down by half before rendering it
    Is that correct?
