Most posts regarding this issue say to restart the computer, look for a second version of SolidWorks running, or replace the gtol.syn file in the SolidWorks file structure.  We have not tried the third option yet (we do not have a computer that this works on).

For drawings created in previous versions and saved in SW 2014, the display of dimensions will toggle between "" and "Ø" in SolidWorks, but always displays as when printed or saved to a .pdf.

It seems that this requires a fix from SolidWorks.  Add this to the long list of things that always worked in the past, but quit working upon installing the "upgrade."  I'm sure it will be fixed by June or July....
