Pasting text from web page - ′

Problem with pasting from web page.
The below line was copied from a web page:
Elevation: 6,486′,
and pasted into a Note field and it displays as:
Elevation: 6,486′,
When this is exported to Tab delimited file it shows as:
Elevation: 6,486′,
I assume this is one of those Unicode problems.
I can export and fix all above errors in the file with a text editor and then import again to solve the existing problems.
But, going forward, when I copy from a web page is there anything I can do to prevent this “′” from happening?
