# little squares instead of greek letters

I don't understand why everytime I write greek letters in my text they are not recognized by the interface and instead it is visualized a square for each letter. In the output everything is fine. Hebrew letters are correctly visualized. I'm using \textgreek{}. The problem occur when I paste greek text taken from the online dictionary or similar. But for instance if I paste the letter pi it is visualized correctly. Any help will be appreciated.

• Even if your TeX engine is able to render the glyphs in the pdf, maybe you don't have a greek font installed on your machine , your “interface” can access? – NBur Jun 25 '18 at 9:41
• It’s possible that you’re using a font in your editor that has π but not other Greek letters. Can you change it to, for example, DejaVu Sans Mono? – Davislor Jun 25 '18 at 10:07
• I have several greek fonts installed on my pc. I use winedt as interface. – user160430 Jun 25 '18 at 10:27
• I changed the font to DejaVu Sans Mono and it worked, but the font is ugly. I used Maiandra GD. Are there some other usable fonts that visualize greek letters correctly? – user160430 Jun 25 '18 at 10:33
