Nginx location match regex for special characters

问题:

I've been trying so many things today and I am just not winning. I have one file in my site which got created by accident with a special character in it. As a result Googlebot has stopped crawling for 3 weeks now and Webmaster tools / Search console keeps notifying me and wanting to retest the url.

All I want to achieve is to configure Nginx to match the following requests and redirect them to the correct location but regex has me stumped on this one.

The unencoded URL string is:

/historical-rainfall-trends-south-africa-1921–2015.pdf

The encoded URL string is:

/historical-rainfall-trends-south-africa-1921%C3%A2%E2%82%AC%E2%80%9C2015.pdf

How can I get a location match for these?

UPDATE:

Still losing my mind, nothing I have tried is working. I get a match with this regex here - https://regex101.com/r/3Lk2zr/3

but then using this

location ~ /.*[^\x00-\x7F]+.* { return 444; }

still gives me a 404 and not a 444

Likewise I get a match with this - https://regex101.com/r/80KWJ8/1 But then

location ~ /.*([^?]*)\%(.*)$ { return 444; }

Gives 404 and not 444
