I am trying to run a parser via proc:execute/system. While if I run it from the command line, it works, it does not, if I run it via BaseX. More precisely, I get the following error:

Traceback (most recent call last):

  File "main.py", line 325, in <module>

    test_data = loader.load(params.test)

  File "/Users/mycomputer/Desktop/Basex9.1beta 2/utils.py", line 57, in load

    for line in f:

    return codecs.ascii_decode(input, self.errors)[0]

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 5390: ordinal not in range(128)
