Yes, the sequence.fallback but I am relaying my observation that adding
korean.allfonts=..
did not work even though sequence.fallback lists korean whereas adding
korean-foo.allfonts=..
and adding korean-foo into sequence.fallback DID work.

So the "first form" being present in the non-working case is the only difference and infer that it hides the usage of allfonts by the fallback sequence.

Someone would need to follow through the code to see why.

And I did not have the korean font pack installed.

Probably this hiding should be regarded as a bug unless we look and see a good reason for it, but it isn't obvious or documented.
