Can not parse well Markdown syntax in code block

[YumaInaura]

example ruby script

require 'redcarpet/compat'

text = <<~TEXT
# Header1

```
# This line parsed as header, not as plain text
echo ok
echo ok
```
TEXT

puts Markdown.new(text).to_html

Outputs

<h1>Header1</h1>


<p>``````</p>

<h1>This line parsed as header, not as plain text</h1>

<p>echo ok
echo ok
```</p>

My verssions

• redcarpet (3.4.0)
• ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]

Hello @YumaInaura,

Actually you need to enable the fenced_code_blocks option; this syntax is not supported by original Markdown, so you should rather write:

Markdown.new(text, :fenced_code_blocks).to_html

Thanks for spotting this anyway !
