vsbRead example works on some files but not others

[skywo1f]

I have a neo-vi->vehicle spy 3 generated file which does not work in the VSBIOExample.py script. It gives me this error:

Traceback (most recent call last):
File "sensibleVSBIO.py", line 13, in
for msg in vsbRead:
File "/usr/local/lib/python3.8/dist-packages/ICS_VSBIO-0.5.1-py3.8-linux-x86_64.egg/ICS_VSBIO/VSBReader.py", line 66, in next
raise ValueError(self.get_error_message())
ValueError: \udc802\udce5

Other files which I generated the exact same way work fine.
