	I18N Tests: IDN display 1


	Previous test Test index Next test   Results

	These tests check whether a user agent displays IDNs (Internationalized Domain Names) as Unicode or punycode in the status bar. User agents that try to detect possible homograph attacks do so in different ways. These tests explore some of those approaches. They are not exhaustive, and the results may change over time, since there is no standard for how to proceed in this respect, and some of the tests are based on lists that may change.

	For more information about what to expect see the article An Introduction to Multilingual Web Addresses <http://www.w3.org/International/articles/idn-and-iri/#work> .

	Mouse over the links in the tests and note whether the domain name is displayed as punycode or Unicode characters in the status bar.

	Run each test twice. First with only en or en-US listed in the browser language preferences, and secondly with the following additional languages in the preferences: Russian, Japanese, German, Greek, Hindi, Armenian, Thai and 'am' (user defined code for Amharic).


	Result of Safari Tests:


	It seems that only Cyrillic and Greek IDNs are displayed in punycode in the status bar of Safari 2.0.1. All other IDNs are displayed in Unicode. And this in both tests. Run 1 (en is the language preference) and Run 2 (with the above additional languages, without amharic).

	In the following, UU means Unicode display in he first and the second run. PP means punycode  display in he first and the second run. There aren't UP or PU.


	1 Latin characters


	1.	charþ.is <http://example.char%C3%BE.is>  (Latin1 character supported by .is TLD, but not .hu TLD)  UU

	10.	charő.fi <http://example.char%C5%91.fi>  (Extended Latin character not supported by .fi TLD) UU 

	Run 1: with HTTP_ACCEPT_LANGUAGE = en. Safari 2.0 displays IDNs  as Unicode in the status bar for all the above 10 cases.

	Run 2 (HTTP_ACCEPT_LANGUAGE different from en-* ) : Same as Run 1.
