I think this delta might be because of v18 characters.

Not sure what is going on, because main doesn't seem to have the environment variable that was in Robin's PR, that lets us switch between v17 and dev.

You need to put -DPOST_SYNCHRONIZED_17 on the maven command line invocation of the generator to generate the 17 files rather than the dev=18 ones.

The merge went poorly here.
I think you want

    static final UnicodeSet validEmailLocalPart =
            new UnicodeSet(
                            "[\\p{XID_Continue}-\\p{block=basic_latin}]",
                            new ParsePosition(0),
                            VersionedSymbolTable.frozenAt(UNICODE_VERSION))

                    .freeze();
