Here are the results of my limited tests for Weibo linkification. Weibo linkifies http://互联网.中国<http://xn--blq510jgwa.xn--fiqs8s> http://教师资格证.公司 http://双一牌.网络 but does not linkify http://牙科設備.中國 http://电邮.在线 http://中国就业网.手机 http://ડાટામેલ.ભારત http://डाटामेल.भारत http://දත්තතැපැල.ලංකා http://இந.இந்தியா http://ดาต้าเมล.ไทย You can see my test Weibo post at weibo.com/1873499154/G8JmVzvY3<https://weibo.com/1873499154/G8JmVzvY3> So, it appears Weibo currently linkifies Chinese character IDNs with TLDs .中国 .公司 or .网络. I have though used a small test set as I do not have time to test hundreds of IDNs, so there may well be other considerations. Anyone have any info on Weibo policy/practice/plans for linkification? I consider Weibo linkification of IDNs to be a positive and encouraging step forward André Schappo On 22 Mar 2018, at 17:42, Andre Schappo <A.Schappo@lboro.ac.uk> wrote: ...and... I have just discovered that Sina Weibo 新浪微博 now linkifies Chinese IDNs😀 Will test with other (human language) scripts.
