Anaconda prompt fail to launch: UnicodeEncodeError: 'utf-8' codec can't encode character '\udd8e': surrogates not allowed

I have Windows 10 x64 en-US and Anaconda3 2021.05. My anaconda prompt was working. Today it failed to launch and shows an error:
# >>>>>>>>>>>>>>>>>>>>>> ERROR REPORT <<<<<<<<<<<<<<<<<<<<<<

Anaconda PowerShell Prompt also fails to launch with similar error:

I searched around and tried everything, including:
Uninstall and reinstall Anaconda.
Upgrade Python to the latest version.
Add PYTHONIOENCODING=utf8 to environment variables.
Add "C:\ProgramData\Anaconda3" and "C:\ProgramData\Anaconda3\Scripts" to PATH.
Removing tempfile.py.
etc., couldn't fix it.
I searched this \udd8e character:
This is an unassigned character within a valid range, meaning it could be designated a valid Unicode code point in the future. However, for now it has no assigned value.
How could I fix this? Thank you very much.

The issue is a non-unicode letter in you PATH environment, which has to be deleted.
Go to your PATH environment file (control panel > system > advanced settings > environment variables) and delete paths under your local user account with non-unicode letters in it.

I had a similar error where setting the PYTHONIOENCODING=utf8 environment variable didn't work, but setting PYTHONUTF8=1fix it.

UnicodeDecodeError when trying to open Idle for Python 3.8

I tried launching idle on the command prompt by using python -i -m idlelib

Try python -i first and see if you can access the idle on the console.
Once you've verified that, you should then open idle on your pc and try import idlelib. If it doesn't load that means that either you don't have that module or its not in you path (which you can fix by finding its location and running import sys; sys.path.append("path/to/module")).
My guess would be that you have multiple versions of python on your pc and when you're running python you are not using the version that has this module.
A person here seems to have had a similar problem, albeit with a different program where the environmental variables they used caused problems. I recommend getting a package like conda. That'll reduce the likelihood of running into these problems immensely.

Python kivy and Linux Mint compatibility issue

I have several programs written in python and kivy language, all of them written in windows environment and working properly. When I tried to run them in Linux Mint, i get a "UnicodeDecodeError". This happens only to the programs that import kivy and it's modules, while all my other python programs work fine. So i wrote a simple kivy program in Linux Mint to see if there is a problem with being written in Win10 and still I get the same error. I've looked it up and saw that others too have similar issues but not the same so i couldn't find an answer to fit my needs.
my releases are: Python 3.4.0 | Kivy 1.9.1 | Linux Mint 17.2 Cinnamon 64bit
Here's my program written in Linux Mint environment:
from kivy.app import App
from kivy.uix.label import Label
class mylabel(App):
def build(self):
return Label(text="Linux Mint!")
if __name__ == "__main__":
mylabel().run()
And here's the error:
Traceback (most recent call last):
File "mintkivy.py", line 9, in <module>

return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 19: ordinal not in range(128)
p.s. I have installed kivy in Linux and after i got the problem i added it in the PyCharm compiler too, and they both produce the same error.
I appreciate the help. Thank you.

My problem is the following:
When I'm running python manage.py collectstatic inside of my Django-project I'm getting this error:

I somewhat know, why it occurs but I'm not able to fit it. (Maybe because I didn't want to break any Django files...)
If you need some more Information I'll happily give it to you.
Thanks.

It works for me export in console.

How to run Google app engine web server on Windows correct?

I tried to run Google App Engine development server using Python 3.2 and Python 2.7, got errors on both:

How do I run it?

It won't work with Python 3.2.
I've had no trouble with GAE and Python 2.7 on Windows 7. It will soon be the officially supported version.
Right now, the officially supported version is Python 2.5, so you should download that if you have any problems getting other versions to work.
I'd suggest something like ActiveState since there are no official binaries for the latest version of Python 2.5.

check this.

I have absolutely the same problem as you, and the problem was bad names (in may case - cyrillic names) in registry over here HKEY_CLASSES_ROOT\MIME\Database\Content Type

As agf mentioned, the problem is you're running the GAE test server with python 3.2 instead of 2.7. To fix this you have a few options:
Specify the python interpreter you want at the command line (eg make a .cmd file):
c:\python27\python dev_appserver.py project_dir
Or redefine the python default interpreter which can either be done by changing the .py handler in "set default programs". Modifying the path environment variables can help as well.
