TEST_F(SymbolsIteratorTest, AllEmojiZWSSequences)
{
    CHECK_RUNS({ { "abcdefghijklmnopqrstuvwxyzabcdefghij"
        "klmnopqrstuvxyzabcdefghijklmnopqrstuvwxyzabcdefghilklmnopqrstuvwx"
        "yzabcdefghijklmnopqrstuvwxyzabcdef",
        FontFallbackPriority::EmojiEmoji } });
}

TEST_F(SymbolsIteratorTest, AllEmojiZWSSequences)
{
    CHECK_RUNS({ { "
