- ~~飘~~

- ~~测试~~
```
  Review this post, you will see this
  
  The strikethrough doesn't work.
  
  If I deleted - ~~飘~~, works well, if I deleted - ~~飘啊飘~~ and - ~~测试~~, left code like following
```
---
layout: post
title: A bug of Jekyll
---

- ~~飘~~
```
  The strikethrough doesn't work too. I tried more Chinese characters, only this one 飘 can cause this issue. It's so strange.

Update@2018-03-09 13:29(GMT+8)

I installed Jekyll at local, and created a new site, and added more text at the bottom in the default markdown(welcome-to-jekyll.markdown) file in _posts folder

~~should be deleted~~

~~飘~~

~~飘飘~~
