Description Florian Weimer 2018-03-15 15:39:17 UTC

This is rather unfortunate:

$ echo xn--iebx.example | LC_ALL=en_US idn2 -d
??.example
$ rpm -qf /usr/bin/idn2
libidn2-2.0.4-3.fc27.x86_64

I would expect an error or the original input string in this situation.  This also happens when calling idn2_to_unicode_lzlz with zero flags.  I do not see a idn2_flags value to change this behavior.

Comment 1 Robert Scheck 2018-03-15 16:02:35 UTC

Reported to upstream https://gitlab.com/libidn/libidn2/issues/46

Comment 2 Florian Weimer 2018-03-30 07:59:27 UTC

This has now been fixed upstream:

https://gitlab.com/libidn/libidn2/commit/6fa9aa172ba262356502aec2a3047610251c6093
https://gitlab.com/libidn/libidn2/commit/dd11133faa276744fb2b11424778c62820bbd547

Would you please release a fixed version to Fedora, ideally back to Fedora 27?  I can help with that if you want.

Comment 3 Robert Scheck 2018-03-30 21:51:04 UTC

After applying patches mentioned in comment #2:

$ echo xn--iebx.example | LC_ALL=en_US idn2 -d
idn2: decode: string encoding error
$
