Error on 'ascii' code on new server

Help
1

My domain is: I have multiple domains hosted on my server.

I ran this command: sudo certbot --nginx

It produced this output:
An unexpected error occurred:
UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xe2 in position 1039: ordinal not in range(128)

My web server is (include version): nginx/1.10.0

The operating system my web server runs on is (include version): Ubuntu 16.04

My hosting provider, if applicable, is: digital ocean

I can login to a root shell on my machine (yes or no, or I don’t know): Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No

I have three domains on a VPS digital ocean, manually setup with vhosts. I am pretty sure they don’t have any ascii error. I am wondering how can I automate the procedure for installing them? After the initial failure I tried this command on one domain (a basic wordpress site, the domain is aerialbodies.gr ) certbot certonly --webroot --webroot-path /my-app-path/aerialbodies/ and it downloaded the certificates. I also tried sudo certbot renew --dry-run and it seems it renews them.

I am wondering should I add them manually now to the vhosts or is there a procedure for being added automatically? Is there some documentation somewhere when you have multiple domains?

I guess you’ve got a â in one of your hostnames somewhere, which isn’t allowed because it isn’t an ASCII character.

Or maybe it’s this bug? in which case the character might be somewhere else in your nginx configuration.

Any suggestions on which files should I look? I am not sure which files the scripts are looking and modifying.

This might provide a clue:

grep -nRP '[\x80-\xFF]' /etc/nginx

Thank you, it worked! Everything worked like a charm. The problematic character was one ’ (I copy/paste some config with comments from the internet and it has included this one as well).
