You can use the Clean function to remove non-printable characters something
like this:

Sheet1.Range("C3").Value = Application.Clean(Sheet1.Range("C2").Value)

This takes the Cell in C2 and removes the non printable characters and
places the resutl in C3

To test it put =CHAR(7) & "Text" in Cell C2...

I have a user that somehow after entering a date in a user form text box
hit Ctrl-Tab a few times. This put some sort of non-prinatble characters
after the input. Then closing the form put the input in a spreadsheet cell
and formulas dependent on this cell errored out. And then macros reading
these errors crashed. Anyway to prevent or detect input like this?
