If they're designed to be used at 50% size, then that's how they should
be used. They would look much too big at full size if that were the case.
Similarly if they're designed to be used at full size, then they should
not be scaled down.

In what context would U+FE45 be used inline as part of the text, other
than in a sentence describing the punctuation mark itself?

How are ruby glyphs related to normal glyphs in the font? (I.e. how
would an application access them)
