In one of our content page, we have a Facebook share using og tags. The page has og:title with content having "#" and "@". This is getting generated in the run time HTML without any issues.
This is the runtime meta tag from webpage:
<meta property="og:title" content="Check out this awesome project, "interesting title of the event ", and see how we can all #interestingproject with test! @test
Saturday, Dec 2nd at 9:00am">
When this is successfully shared to Facebook, the title is displayed without "#" and "@". When I try to scrape the URL, the og:title shows up without "#" and "@". Tried to do a JavaScript encodeURI of this value. But does not help.
Tried to google as well search through Facebook docs. I could not find any explanation for this. OpenGraph documentation mentioned the value of the tags are Unicode string literals.
Does Facebook strip these characters?
