The Solid Edge fonts didn't get installed that have the symbols.
Search your FONTS folder to make sure you have all 13 Solid Edge fonts installed. The 2 important ones are "Solid Edge ANSI GDT..." and "Solid Edge ISO GDT..."
Thanks swertel.
This is already verified. My symbols are not there, but a day before I had symbols. I think an error occur there.
If you have other ideas please don't hesitate.
