Sometimes, you may want use html-pipeline to manage the Plain Text process.
For example:
- Match mentions, and then send notifications.
- Convert Mention / HashTag or other text into other format.
But in HTML mode, it will escape some chars (", ', &) ... We don't wants that.
So, there have NewPlainPipeline method for you to create a plain mode pipeline without any escape.
NOTE: For secruity, this pipeline will remove all HTML tags
