I mostly frequent the Marriott and United fora here, and for a while, some users' posts have been expanding apostrophes (and sometimes double-quotes) into what appears to be a horizontal tab. As the image below will show, however, it's not all quotes.


This is from the https://www.flyertalk.com/forum/unit...ft-23rd-6.html thread. Note that fezzington's apostrophe didn't expand, where as JOSECONLSCREW28's did.

I've noticed this behavior in both of the aforementioned fora. I wonder if it's somehow related to (possibly) some users cut-and-pasting from an external editor that uses "smart quotes"?

Mac OSX, latest version. Google Chrome, latest version.
