UTF8 string / regex issue

[apismensky]

Regex: \x{ff15}\x{ff10}\x{ff17}\x{ff15}\x{ff10}[\x{ff10}-\x{ff19}]{7}
Input string: ５０７５０７８３２４０１
Matches in regex101, but does not match with vectorscan.
Step to reproduce:

TEST(utf8, charclass) {
    vector<pattern> patterns;
    patterns.push_back(pattern(R"(\x{ff15}\x{ff10}\x{ff17}\x{ff15}\x{ff10}[\x{ff10}-\x{ff19}]{7})", HS_FLAG_DOTALL | HS_FLAG_PREFILTER | HS_FLAG_MULTILINE | HS_FLAG_CASELESS | HS_FLAG_UCP | HS_FLAG_UTF8, 1));
    const char *data = "５０７５０７８３２４０１";

    hs_database_t *db = buildDB(patterns, HS_MODE_NOSTREAM);
    ASSERT_NE(nullptr, db);

    hs_scratch_t *scratch = nullptr;
    hs_error_t err = hs_alloc_scratch(db, &scratch);
    ASSERT_EQ(HS_SUCCESS, err);

    CallBackContext c;
    err = hs_scan(db, data, strlen(data), 0, scratch, record_cb,
                  (void *)&c);
    ASSERT_EQ(HS_SUCCESS, err);

    EXPECT_EQ(1, countMatchesById(c.matches, 1));
    err = hs_free_scratch(scratch);
    ASSERT_EQ(HS_SUCCESS, err);
    hs_free_database(db);
}

It fails when I run it locally (MacOS M1).
