'charmap' codec can't decode byte 0x9d in position 1003: character maps to <undefined> code example

Example 1: UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 6148: character maps to

Add encoding:
	
	file = open(filename, encoding="utf8")

Example 2: UnicodeDecodeError: 'charmap' codec can't decode byte 0x8f in position 550: character maps to

# process_lines DID NOT WORK AT FIRST
# I had fogotten that the EOL (end of line) charcter/values were

# .strip() got rid of them, no problem



# All this does is print out the line.

Main Routine

#Orders is a BIG file encoded UTF-8
#Orders1 is a SMALL file encoded UTF-8 (1st 5 entries of Orders)


#Initially I had an error
#    'utf-8' codec can't decode byte 0xe2 : invalid continuation byte error
#
# This was solver with the following:
#                                                                      encoding="UTF-8"


counter=0


with open('orders1.txt', 'r',encoding="UTF-8") as f:
    for line in f:
        counter +=1    
        xx=process_lines(line, counter)
        if xx=='x':
            break
