I am not sure when it started happening, but, Weibo now linkifies some Chinese IDNs. Here are the results of my limited tests.
Weibo linkifies the following:
http://互联网.中国
http://教师资格证.公司
http://双一牌.网络
Weibo does not linkify the following:
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
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 for linkification?
I consider Weibo linkification of IDNs to be positive and encouraging step forward
