Convert to HTML fail when header is only CJK characters

[milligramme]

runing 2.0-beta.12.26

Header item will convert to H1-6 with id.
If the contents is only CJK chars, last quotation mark for id is short.

here is a sample.

# 第一階層

top level

## 第二階層

second level

## 第三階層

third level

output from Convert Document to HTML

<h1 id=">第一階層</h1>

<p>top level</p>

<h2 id=">第二階層</h2>

<p>second level</p>

<h2 id=">第三階層</h2>

<p>third level</p>

I expect this output.

<h1 id="">第一階層</h1>

<p>top level</p>

<h2 id="">第二階層</h2>

<p>second level</p>

<h2 id="">第三階層</h2>

<p>third level</p>

this probrem seems to be caused by redcarpet.rb vmg/redcarpet#538

Going to close this in favour of the upstream issue.

installing redcarpet v3.4.0 fixed this issue.

$ sudo /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/gem install redcarpet
