# These are tests of the UnicodeSetBuilder.
# The format is:
# <builder_format> ; <old_UnicodeSet_format_or_error>
# The second field is empty if the formats are the same.
# It is the error code if an error is expected.
#
# The differences in format are that the new format has:
# && and -- defined as in ICU4C Regex
# ~~ defined as symmetric difference, as in UTS#18
# Various quirks for compatibility with Java Regex
