How to preserve the char case of host name returned from QUrl::host()?

Sauntor

It seems that QUrl::host() always returned a lower case string, can I get the original host name(keep case unchanged)?

For example:

QUrl url("MyProtocol://MyHost/kkkk");
// the codes which fix this issue go here
Q_ASSERT(url.host() == "MyHost");

The docs for QUrl refer to RFC 3987:
...
When an IRI uses components of the generic syntax, the component syntax equivalence rules always apply; namely, that the scheme and US-ASCII only host are case insensitive and therefore should be normalized to lowercase. For example, the URI
"HTTP://www.EXAMPLE.com/" is equivalent to "http://www.example.com/".
...

So the odds are against you finding the original case of the host :-(
