Need to replace HTML special characters to their corresponding HTML entities

[jgkim]

I can find some HTML special characters, such as “, ”, ‘, and ’, in the content.

We should replace them with their corresponding HTML entities (e.g. “, ”, ‘, and ’), or for curly quotation marks, we can just use plain quotation marks and let Markdown automatically handle them.

We should replace quotes to "normal" quotes and let markdown automatically handle them.

Even if I replaced all the quotation marks into their plain forms (#200), some pages still have HTML special characters such as &, and it could be problematic to automatically replace them with their HTML entities (e.g., &).

Why do you think it would be problematic?

@rgrp Since all the HTML entities start with &, it's impossible to simply find & replace every occurrence of & to &.
