I use inline to create a blog like the below:

[[!inline  pages="./bugs/* and !./bugs/done and !./bugs/discussion and 
!link(patch) and !link(./bugs/done) and !./bugs/*/*"
actions=yes rootpage="./bugs" postform="yes" postformtext="请用一句话简述问题,然后点击 Edit 按钮添加具体细节" show=0]]

When I use posform to add a new page, it show:

Error: bad page name

Its url include a %2F, like below:

I use ikiwiki 3.20180311

I have found that it is not "%2F"'s problem, it just that inline directive can not deal with Chinese char, the below link can work

I don't think this is actually caused by the Chinese text. The problem is that you used rootpage="./bugs", which leads to the blog request handler generating an invalid page name. If you change it to rootpage="bugs" does that fix the error?

Ideally either the inline directive or the blog request handler would understand and remove ./, if it's something that makes sense in this context. --smcv

I have found the problem, it is inline plugin can not decode_utf8 "from", the below is patch:
