290275 - Add whitelist of safe top-level domains for IDN (Opera method)

Status: RESOLVED DUPLICATE of bug 286534

(Core :: Networking, defect)

Description

[u115577]

All IDN urls are currently displayed as Punycode by default. Whitelist of safe
TLDs like Opera is needed to resolve this IDN problem more smartly.
http://www.opera.com/windows/changelogs/800b2/

I suggest new pref like this:
pref("network.IDN_TLDs_whitelist", "no, jp, de, se, kr, tw, cn, at, dk, ch, li");

If IDN url matches whitelist, the url should be displayed as Unicode whether
"network.IDN_show_punycode" pref is true or false.

I don't think that this way is best.
Because there is bug 283016. We cannot trust the sub-domain always.
I think that better way is the way of Safari.
Safari has blacklist of char. In this way we can trust all TLD and all sub-domain.

Attachment: whitelist of Safari (IDNScriptWhiteList.txt)

Safari has whitelist of char, not blacklist.

Sorry. I don't know it.
I don't like the way of Safari too...
Because on Safari, we cannot use inter-ideograph(Kanji).

Should we create blacklist of char?
# Is the way wrong for performance?

Isn't this a dup of bug 286534? (and bug 286535 for the char-blacklist)

Comment 7

[Jungshik Shin]

Yes, this is a dupe. I'm just resolving it as a dupe of bug 286534 because
that's what the summary line talks about.

Bug 286534 is about blacklist and different from Opera method.
Solution of Bug 283016 may be bug 286535.

Comment 9

[Erik van der Poel]

Opera 8.0 beta 3 allows the user to switch from a whitelist to a blacklist:

I don't think so. See the summary line of that bug. It's about a generic method
to dis/enable rendering IDNs with punycode depending on TLD.
