When certain text including smart quotes is pasted into the edit window for a page, and formatting (like bold, italic, strike, or under) is applied to that text, the resulting page will show the formatting macro characters, and no formatting is applied.

For example, this text should be italicized in the previewed page:

importantSomehow "textInSmartQuotes" importantSomehow

However, the _'s will be visible instead, and the text is not italicized.
