Currently when a character is requested that is not found in the
selected font we first look in other fonts that are already loaded that
include some of the requested Unicode range. If not found in any of
those we then look in unloaded fonts. But multiple fonts often have
overlapping coverage, so this means you can sometimes get a character
from different fonts depending on the order they are requested. Since
the design of that character could differ, this can lead to visual
changes. This PR changes the fallback search to do so in a consistent
order, not favoring loaded or unloaded. This does not lead to any
measurable performance changes in testing.
