Alt text with comma adds extra, broken og:image

For this scenario what you have to do is change the separator to something else instead of the default comma, then tags will output as expected.

I also stumbled upon this bug.

As a solution, I removed the comma, but now the alt text is not grammatically correct.

Please try the new setting that lets you change the separator from a comma to something else, that should resolve the problem.

Thanks, that did the trick but wouldn't it still be better to not interpret this character in fields that do not allow multiple values?

Or wouldn't it be better to replace the default , character with a less common unicode character such as 𒐫? Or will that introduce new problems on systems without unicode support?
