        "y": [
            "aaaaaa\u0142 bbbbb"
        ]
    }
}

result = x | deepdiff.grep({'foo': 'bar'}, verbose_level=2)

Expected behavior
return matched results as usual

OS, DeepDiff version and Python version (please complete the following information):

Thanks for reporting this bug. I have made a fix and will post you once that is published. Just one note: grep is not very useful when you are searching for a nested object inside another nested object. The reason is that grep will convert your {'foo': 'bar'} into a string of "{'foo': 'bar'}" when searching. It works correctly when searching for integers or strings inside a nested object though:

    def test_number_in_list2(self):
        obj = ["a", "10", 10, 20]
        item = 10
        result = {"matched_values": {'root[2]'}}
        assert DeepSearch(obj, item, verbose_level=1) == result

    def test_number_in_list3(self):
        obj = ["a", "10", 10, 20]
        item = "10"
        result = {"matched_values": {'root[1]'}}
        assert DeepSearch(obj, item, verbose_level=1) == result
