Is There a Way to Match Any Unicode non-Alphabetic Character?

I have some documents that went through OCR conversion from PDF into HTML. Because of that, they wound up having lots of random unicode punctuation where the converter messed up (i.e. elipses, etc...). They also correctly have a bunch of Non-English, but still Alphabetic characters, like é, and Russian characters, etc...

Is there any way to make a Regex that will match any unicode alphabetic character (from alphabets of any language)? Or one that will only match non-alphabetic characters? Either one would be really helpful and awesome. I'm using Perl, if that changes anything. Thanks!
