[UA-discuss] UA for Egyptian Hieroglyph IDNs

This is a design decision by the browser team.  It’s not a Windows-specific behavior per se, though it does inherit the Language Preferences settings from the OS.

Here’s an example.

You can see that the tab text (which displays webpage Title), which is defined by the web page, is shown in Unicode.  But the address bar, whose behavior is defined by the app, shows the URL in punycode because Egyptian Hieroglyph is not set as a preferred language on my Windows machine.

I did not install an EH lang pack to test, but I have played with my Japanese Language Pack and confirmed the behavior.

No, I only tested on Mac OSX😜😀 I have the Google Noto Egyptian Hieroglyph font installed https://www.google.com/get/noto/<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.google.com%2Fget%2Fnoto%2F&data=02%7C01%7Cmarksv%40microsoft.com%7C396988e0fb0a479df89d08d4ae417a3a%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636325043641917707&sdata=7Qh7Iam%2By1xeAfGFB4KB0G%2BWnoUukblkmlVmcJtwrJY%3D&reserved=0>

I am intrigued by what Windows is doing as it seems unlikely that the presence/absence of an appropriate language pack is the only criteria for determining whether the Unicode or the punycode forms are displayed on Windows. Maybe it is just an initial criteria. Have you tried installing an Egyptian Hieroglyph language pack?

PS. I have now typed Egyptian Hieroglyphs so many times I no longer need to lookup the spelling in a dictionary😀

You didn’t test IE or Edge?  You are breaking my heart 😉

Behavior is the same as on other browsers, though.  It has to do with installed fonts.    I see punycode for any script that I don’t have an installed language pack.

I have tried some Egyptian Hieroglyph IDNs http://egyptianhieroglyphic.com/egypt/egyptian-hieroglyphics/<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fegyptianhieroglyphic.com%2Fegypt%2Fegyptian-hieroglyphics%2F&data=02%7C01%7Cmarksv%40microsoft.com%7C49703ac825fa4e178be508d4adbc0e74%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636324470589035104&sdata=vsSw02BcEgf4Fran6UFa4RQsyByPQy51ih%2FO46uqE9Q%3D&reserved=0> with Safari, Chrome, Firefox and Opera and they all show punycode instead of Unicode. The Unicode form should be displayed because :-

① The Egyptian Hieroglyph Unicode characters U+13000➜1342E are PVALID https://tools.ietf.org/html/rfc5892<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftools.ietf.org%2Fhtml%2Frfc5892&data=02%7C01%7Cmarksv%40microsoft.com%7C49703ac825fa4e178be508d4adbc0e74%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636324470589035104&sdata=MwmUm9YbyRzE%2F5a9IijwMc26%2FHnJvmWxmuyyLBSizkE%3D&reserved=0>
② Unicode Egyptian Hieroglyphs have the General Category Lo (Letter other) which makes them valid in IDNA2008
③ Registry Verisign offer registration of Egyptian Hieroglyph Domain Names in TLDs .com .comsec .name .net .verisign .ком .קום .कॉम .नेट .คอม .كوم .コム .大拿 .点看 .닷넷 .닷컴. There may well be other Registries which offer registration of Egyptian Hieroglyph Domain Names.

If a browser manufacturer would like a language tag for Egyptian Hieroglyphs then I think egy-Egyp would be appropriate.

I realise that Egyptian Hieroglyphs could be thought of as an exception as it is an ancient Script. Maybe browser manufacturers should handle them as an exception and explicitly display Egyptian Hieroglyphs in Unicode form as opposed to more general encompassing rules that may well result in Egyptian Hieroglyphs being displayed as punycode.
