The above code can only create text files in ANSI format. How to create UTF-8 files?

Answer 1

In fact, the code of the subject can create UTF-8 files, but because there is no content written in the file, the empty txt file does not have encoding. Write some UTF characters and try again and it will be OK

    f=codecs.open(path,'w', 'UTF-8')
    f.write("中文")
    f.close()

Open the c.txt file again and it will be UTF-8.
