Parsing a standard STDF generated by Teradyne Ultraflex platform that contains ANSI characters not compatible with utf-8 causes UnicodeDecodeError to be thrown.

Test code:

for REC in STDF.records_from_file(filename):
    record = REC.to_dict()

Error:
Exception has occurred: UnicodeDecodeError 'utf-8' codec can't decode byte 0x96 in position 57: invalid start byte

 

Suggested Solution:
Change bytearray.decode() error handler from 'strict' to 'replace'
