问题
I am trying to push some files up to s3 with the AWS CLI and I am running into an error:
upload failed: ... An HTTP Client raised and unhandled exception: unknown encoding: idna
I believe this is a Python specific problem but I am not sure how to enable this type of encoding for my python interpreter. I just freshly installed Python 3.6 and have verified that it being used by powershell and cmd.
$> python --version
Python 3.6.7
If this isn't a Python specific problem, it might be helpful to know that I also just freshly installed the AWS CLI and have it properly configured. Let me know if there is anything else I am missing to help solve this problem. Thanks.

I had the same problem in Windows.
After investigating the problem, I realized that the problem is in the aws-cli installed using the MSI installer (x64). After removing "AWS Command Line Interface" from the list of installed programs and installing aws-cli using pip, the problem was solved.
I also tried to install MSI installer x32 and the problem was missing.

As a workaround, put the following import statement into the aws-script.py file.
import encodings.idna
Full path on 32-bit version is c:\Program Files (x86)\Amazon\AWSCLI\bin\aws-script.py
Full path on 64-bit version is C:\Program Files\Amazon\AWSCLI\bin\aws-script.py

I've come across the same error and fixed by changing the order of AWC CLI and Python path:
Before:
PATH=C:\Program Files\Python35\Scripts\;C:\Program Files\Python35\;...;C:\Program Files\Amazon\AWSCLI\bin\;...
After:
PATH=...;C:\Program Files\Amazon\AWSCLI\bin\;...;C:\Program Files\Python35\Scripts\;C:\Program Files\Python35\
Looks like Python3 influences AWS CLI, which is just a cmd calling Python program.

On Windows, this is probably an issue with the AWS-cli tools being installed using the MSI installer. It seems the best way to fix this issue is to use the aws-cli tools installed with python.
Prerequisites: Python3 and Pip3
Verify you have Python and Pip installed
C:\> python --version
Python 3.7.1
C:\> pip3 --version
pip 18.1 from c:\program files\python37\lib\site-packages\pip (python 3.7)
Uninstall the AWS-CLI tools MSI installer
Install the aws-cli tools with pip
C:\> pip3 install awscli
Check if aws-cli is in your path already ; if not, add it
C:\> where aws
C:\Program Files\Python37\Scripts\aws
If not, locate where the aws-cli tools are deployed and add the path to your PATH environment variable (can be set in Control panel > System > Advance system settings > Environment Variables...).
Below, common path of the deployed AWS cli tools:
Python 3 and pip3 – C:\Program Files\Python37\Scripts\
Python 3 and pip3 --user option on earlier versions of Windows – %USERPROFILE%\AppData\Local\Programs\Python\Python37\Scripts
Python 3 and pip3 --user option on Windows 10 – %USERPROFILE%\AppData\Roaming\Python\Python37\Scripts

Even I was facing same issue. I was running it on Windows server 2008 R2. I was trying to upload around 500 files to s3 using below command.
aws s3 cp sourcedir s3bucket --recursive --acl bucket-owner-full-control --profile profilename
It works well and uploads almost all files, but for initial 2 or 3 files, it used to fail with error: An HTTP Client raised and unhandled exception: unknown encoding: idna
This error was not consistent. The file for which upload failed, it might succeed if I try to run it again. It was quite weird.
Tried on trial and error basis and it started working well.
Solution:
- Uninstalled Python 3 and AWS CLI.
- Installed Python 2.7.15
- Added python installed path in environment variable PATH. Also added pythoninstalledpath\scripts to PATH variable.
- AWS CLI doesnt work well with MS Installer on Windows Server 2008, instead used PIP.
Command:
pip install awscli
Note: for pip to work, do not forget to add pythoninstalledpath\scripts to PATH variable.
You should have following version:
Command:
aws --version
Output: aws-cli/1.16.72 Python/2.7.15 Windows/2008ServerR2 botocore/1.12.62
Voila! The error is gone!
