}'

curl -i -X GET "http://127.0.0.1:9080/中文/foo?arg=10" -H "Host: [example.com](http://example.com/)
curl -i -X GET "http://127.0.0.1:9080/%E4%B8%AD%E6%96%87/foo?arg=10" -H "Host: [example.com](http://example.com/)"

request APISIX

curl -i -X GET "http://127.0.0.1:9080/%25E4%25B8%25AD%25E6%2596%2587/foo?arg=10"

upstream nginx log:

127.0.0.1 - - [09/Sep/2022:16:37:46 +0800] "GET /%25E4%25B8%25AD%25E6%2596%2587/foo?arg=10 HTTP/1.1" 200 35 "-" "curl/7.58.0"

APISIX will not change your URL, it just forward your URL if you don't use any plugin.

So where is the problem?

Many web server, like nginx, it will decode the url-encoded URL before match the route.

So I guess you could encoded your URL twice like the example above.
