if you haven't run into a solution yet for your encoding issue on the XML...

my_str = "hello world"
my_str_as_bytes = str.encode(my_str)
type(my_str_as_bytes) # ensure it is byte representation
my_decoded_str = my_str_as_bytes.decode()
type(my_decoded_str) # ensure it is string representation

encode to bytes and decode into your UTF-8 ?

Default string encoding for python 3 is utf-8 (which is good). https://docs.python.org/3/howto/unicode.html#the-string-type

Currently:

• xml_check.py is more "check if xml is well-formed" than validation against a schema
• Errors (e.g.  / "<0x0b>" in the [not-quite-UTF8] XML export from EMu) are added to an error-log with the specific line in the xml where something is not well-formed -- e.g.:

2021-07-13 08:11:50.340441 - File Input: /home/data/2021-6-24/xml50704-195636.000000 : Error : not well-formed (invalid token): line 2579, column 50

(decision - that suffices)
