Hi all, I really hope someone can assist me as I am out of ideas to get a regex working for this location match.

I need a location regex to match the following requests and redirect them to the correct location but regex has me totally 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? It's literally only one pdf file that got uploaded with a messed up filename and now I am unable to redirect search engines to the correct file.

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 ???? I might just add my regex sucks

SOLVED with this.

location /resources {
location ~* \.(jpg|jpeg|png|gif|ico|css|js|pdf)$ {
if ($request_uri ~ .*%.*) { return 301 https://example.com/resources/weather-documents/historical-rainfall-trends-south-africa_1921_2015.pdf; }
if ($request_uri ~ .*[^\x00-\x7F]+.*) { return 301 https://example.com/resources/weather-documents/historical-rainfall-trends-south-africa_1921_2015.pdf; }
}
