The behavior of handing fonts "Timesroman", "Helvetic" and "Courier"
is different between Firefly and Ladybird (and merlin), especially for
heavyweight awt components. these three fonts fallback to use "Sansserif"
on Firefly, but this fallback does not happen on Ladybird due to a code
regression when we migrated Firefly to Ladybird. The result is that
"no-English" characters, like Japanese, are not being displayed correctly
when using these three fonts.
