Escape special characters

[gingur]

Characters such as # ~ - [ ] ( ) > should be escaped like how characters * _ are.

Use case:

• Visit https://react-rte.org/demo
• Type the following

# heading
~~strike~~
- list
[title](url)
> blockquote

• Switch to markdown tab
• Cut markdown
• Paste markdown

You'll notice the dehydrated state is not properly escaping these MD characters and when rehydrated from MD not all exported content like blockquotes are recreated.

I was wondering if there had been any progress on resolving this issue?
