Ok so in summary. It's not a hard and fast number of characters, but looks like its pixel widths. Also google can ignore the title tag if it has deemed the title tag non-descriptive?
So two title tags:
<title>The Legend of Captain Jack Sparrow Opens at Disney’s Hollywood Studios</title>
appears as:
legend-captain-jack-sparrow-1149.html - Orlando Visiting
<title>Pirates of the Caribbean: The Legend of Captain Jack Sparrow | Walt Disney World News</title>
appears as
Pirates of the Caribbean: The Legend of Captain Jack Sparrow ...
Is it the pipe in the title affecting this because I wouldn't say it the title tag physical width or number of characters?
