While placing text on a schematic I could not get the ohm symbol to display, I can enter Alt+0937 but it does not place the Ω yet if I click on the text to edit it I can enter the Atl+0937 ohm symbol , it does show in the editor but when saved it does not show in the schematic.
DipTrace 4.0.02
I found the issue: Change font to True Type and it works
