Bug 39089 – Domain names in Russian '.рф' domain are displayed as punycode

• Component: Page Loading
• Status: RESOLVED FIXED

[Alexey Proskuryakov]

Steps to reproduce:
1. Open http://президент.рф

Expected results: address bar shows just this.
Actual results: it's converted to punycode.

There is no security risk in allowing Cyrillic characters in this TLD - to the contrary, Latin ones aren't allowed per registrar rules.

I'd like to see more use of early-return so the nesting could be a bit more shallow.

Also, we should find a way to make regression tests for this.

Some examples of what needs to be tested:

shouldBe("presentDomainName('президент.рф')", "'президент.рф'");
shouldBe("presentDomainName('президент.рф.')", "'президент.рф.'");
shouldBe("presentDomainName('www.президент.рф')", "'www.президент.рф'");
shouldBe("presentDomainName('почта.президент.рф')", "'почта.президент.рф'");

shouldBe("presentDomainName('0ж9.рф')", "'0ж9.рф'");
shouldBe("presentDomainName('туда-сюда.рф')", "'туда-сюда.рф'");

shouldBe("presentDomainName('прeзидент.рф')", "'punycode'"); // spoof: Roman "e"
shouldBe("presentDomainName('caxap.рф')", "'punycode'"); // spoof: all characters in "caxap" are Roman
