Weird characters in CSS

Hi, I am using the plugin and have had only good experiences with it.
Just as I was browsing posts now I noticed that one of the quote blocks had a weird symbol where a guillemet was suppose to be.

It isn’t there on the other posts. I checked the CSS sheet for it, and it looks like it had some encoding issues or something.

Here’s just a snippet, so you get what I mean
.bt-circle:before{content:"ï‚Œ"}.bt-hexagon:before{content:""}.bt-octagon:before{content:"ï‚Ž"}.bt-angle-up:before{content:""}.bt-angle-down:before{content:"ï‚‘"}.bt-angle-left:before{content:"ï‚’"}.bt-angle-right:before{content:"ï‚“"}.bt-angles-up:before{content:"ï‚”"}.bt-angles-down:before{content:"ï‚•"}.bt-angles-left:before{content:"ï‚–"}.bt-angles-right:before{content:"ï‚—"}.bt-arrow-up:before{content:""}.bt-arrow-down:before{content:"ï‚™"}.bt-arrow-left:before{content:"ï‚š"}.bt-arrow-right:before{content:"ï‚›"}.bt-bar-chart:before{content:"ï‚œ"}.bt-pie-chart:before{content:""}.bt-circle-arrow-up:before{content:"ï‚ "}

Specifically for this blockquote,
.article-content blockquote:before{top:-34px;left:-11px;content:"«";color:#ab7000;font-size:5em;position:absolute}
(It actually showed on the page as ‘«’)

I tried reloading and a different browser, and the blockquote looked normal again. I once again opened the stylesheet, and it looked the same (was also same filename on the file, so it didn’t change).
