I have python script which display Unicode message to the terminal while executing. So i want to display that message in the web page while the process runs. I was able to run the

The comment of @snakecharmerb is the solution.

You must set the PYTHONIOENCODING variable before launching the child Python process to allow it to correctly encode its output in UTF-8. Then you have just to decode what you get in the parent:

from subprocess import Popen, PIPE
import osos.environ['PYTHONIOENCODING'] = 'UTF-8'
scripts = os.path.join(os.getcwd(), 'scripts')
p = Popen(["python", "tasks.py"],bufsize=0, cwd=scripts, stdout=PIPE, stderr=PIPE)
out,err = p.communicate()
print(out.decode())

If you have Python>=3.6, you can directly get out and err as unicode strings:

os.environ['PYTHONIOENCODING'] = 'UTF-8'
scripts = os.path.join(os.getcwd(), 'scripts')
p = Popen(["python", "tasks.py"],bufsize=0, cwd=scripts, stdout=PIPE, stderr=PIPE, encoding='UTF-8')
out,err = p.communicate()
print(out)
