Using ” apostrophe ” in captions breaks plugin

First I’d like to thank you for this great plugin.
It works out of the box without issues; 99,9% of the time.

I’ve encountered a special case which breaks the plugin.
When any captions with apostrophe (“) are being used the captions won’t show the full text; breaking the <html> because of the extra ” within the code.

Do you see any solution to this problem?
Thank you
