Answer 1

You can use the open method from the codecs module (instead of open(file,'w') ):

import codecs

fileNames = ['file1.txt', 'file2.txt']

with codecs.open('file3.txt', 'w', 'utf-8') as outfile:
    for fname in fileNames:
        with open(fname) as infile:
            for line in infile:
                outfile.write(line)

Answer 2

How about:

line.encode('utf-8')

in case it's not already encoded with utf-8. It should be though, when both files are initially utf-8. You can also open the file in python with a given encoding:

file = open("C:\test.txt","r", encoding="utf-8")
