Wrong parsing with chinese

[frankxiongsir]

Thanks for great project!

Jazzy just works fine with english characters but I found that it has some problem when using unicode characters (like Chinese.) in jazzy.json like below:

"theme": "fullwidth", "documentation": "doc/MarkDown/*.md", "custom_categories": [{ "name": "简介", "children": [ "名词说明", "功能介绍", "工程配置", ] }]

Jazzy can’t generate 名词说明.html that match the dictionary key ‘children’

This is related to the discussion in #945. As you've found out, non-ascii characters in documentation file names get stripped out. When there are no other characters in the filename, the thing doesn't work at all.

I think I got disheartened by the back-compatibility part last time I looked at it, will have another go!
