Why inserting the Pi and others Math symbols using Fonts like greeks,symbol,etc are shown as a Rhombus - LibreCad 2.1.3 & 2.2.0.2 for Windows 10

This happens when the used font doesn't support that specific character.

Thanks for help. Following your instructions I found: Font Type= symbol Text = "P" I got the Pi symbol (squared representation of Pi) I also found the classical representation of Pi (the curved form of Pi) using Font = "greekc " and Text ="p" for classical double traced Pi , or using Font = "greeks " and Text ="p" for classical single traced Pi

Did you try the lower case "p" and Greek fonts?

I would prefer the classical representation of Pi
(the curved form of Pi).
