NAV 2009 Classic Dataport question

Hi Folks -

One of our customer has a value of 53¼ × 79½ in a field called Width which is of data type Text. When they export this field via dataport it exports it like looks like 53< X 79} in the notepad when they open the file. All other fields are fine.

Does anyone know any solution for this. Any help is highly appreciated.
