YaLaFi insists in using \Lib\encodings\cp1252.py even in a UTF-8 environment

[csrabak]

In a Windows 10, home ed, single language in a CMD shell, where:
C:\>chcp Página de código ativa: 65001

I.e., UTF-8 code page.

When running this per example command line:
py -3 -m yalafi.shell --server lt --output plain --encoding UTF-8 --language pt-BR text.tex > reslts.text

I get:

Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main

    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
UnicodeEncodeError: 'charmap' codec can't encode character '\u2082' in position 13: character maps to <undefined>

Which I cannot understand why YaLaFi "prefers" the CP1252 encoding even if told via command line and the shell in UTF-8!

Is there some way to parametrize YaLaFi to avoid this issue?
