Button to validate URLs

We had an issue with a campaign link that apparently had an 'invisible space' behind it.

In Marketo itself, the link works perfectly fine and redirects you to the correct page. However, when sending the actual email out, Marketo all of a sudden puts something like '%20' behind the link (because apparently there is a space at the end of the web link).

Could there be a button one could press to validate all URLs?  Based on user-specified config (checkboxes), this feature could check for extraneous spaces as well as missing UTM codes and mktNoTok classes, for example.
