Should apostrophe's be stored from a form into a database as ’ or as is '

If Im pasting articles into a database from another website do I need to convert the string on posting or leave them as it is.

Depends what method you are using. If you are using MySQLi or PDO, then parameter binding will take care of it.

Thanks Im using mysqli.
So if I bind paramaters it will take care of itself ?.

It's always best to sanitize input anyway, but when using binding the apostrophes aren't an issue.

How would I go about sanitizing ?.
Also a lot of earlier records in my database pre changing mysql to mysqli now show with weird symbols instead of apostrophe's any idea how to rectify that problem as below ?.
