UnicodeDecodeError: 'utf-8' codec can't decode byte... invalid continuation byte

[Adam5i]

I am using a search engine - pyserini (anserni) - which depends on pyjnius. Anserini is based on java and pyserini is using pyjnius to operate with anserini.
Returning the search hits, anserini holds them in a java object and when I tried to return the hit content (text) of one of the hits, I got the following error

Traceback (most recent call last):
  File "/my_directory/utils.py", line 26, in doc_content_from_hits
    return np.array(list(map(lambda result: hit, hits)))
  File "/my_directory/utils.py", line 26, in <lambda>
    return np.array(list(map(lambda hit: hit.content, hits)))
  File "jnius/jnius_export_class.pxi", line 336, in jnius.JavaField.__get__

  File "jnius/jnius_conversion.pxi", line 155, in jnius.convert_jobject_to_python
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xed in position 46: invalid continuation byte

Other than that with that hit, it is working fine.
I'm using Python 3.7.3 on Debian, Java 8 and

Cython==0.29.14
pyserini==0.7.0.0
pyjnius==1.2.1

I saw two similar issues that existed before: #183 #285
Is there any way I can solve that issue on the pyjnius side?
