1972	Use of IRIs in redirect responses causes nginx to violate HTTP RFCs	Avamander		"For example when you do this in a server block:
```
return 301 https://ǐri.domain
```

Then nginx nicely sends `ǐri.domain` to the client, which can cause issues with things that except ASCII URIs as described in the standard.

Nginx should auto-punycode or warn about such return sentences."	defect	closed	minor		nginx-core	1.17.x	wontfix			4.15.0-88-generic	nginx/1.17.10
