OT specs theoretically allow character composition on-the-fly from a base glyph and combining marks plus anchors without encoded characters being part of the font (
a
+¨
is sufficient,ä
needn't be present).
Though this works in Chrome, in most applications if the pre-composed character is missing from the font, the application will use a fallback font and will not try the decomposed form first.
