Description Jxck 2015-04-11 01:07:58 UTC 
I found this test about url spec.


```
# Basic canonicalization, uppercase should be converted to lowercase
http://ExAmPlE.CoM http://other.com/ s:http p:/ h:example.com
```

https://github.com/w3c/web-platform-tests/blob/master/url/urltestdata.txt#L100


but I couldn't find about this in spec.
which part mentions it ?
Comment 1 Anne 2015-04-11 06:43:21 UTC 
That is part of https://url.spec.whatwg.org/#concept-domain-to-ascii which references http://www.unicode.org/reports/tr46/#ToASCII which references http://www.unicode.org/reports/tr46/#Processing which does some mapping based on a table which lowercases.
