That may be our fault, to a significant degree. Did you read my mail
from yesterday, over on the "CREATE COLLATION does not sanitize ICU's
BCP 47 language tags" thread? I think that we've been incorrectly
specifying the locale name that is passed to ucol_open() this whole
time. At least, for ICU versions prior to ICU 54. This will need to be
addressed very soon.
