Help with Search Please

Long time since I posted here

Has anyone got some Regex/search that will find punctuation that hasn't got a space after

EG

‘Oh, I don’t know,’Jessie groaned

Missing space after ’ or before Jessie

What I want to find is ,’

Not followed by a space

Quite a few of them and not just speechmarks but question marls, exclamation marks. Really hard to spot

I'm using Sigil

Thank you
