you should provide more information to the community if you expect answers.
Which LibreCAD version do you use?
What have you tried so far?
What does not happen?
Maybe a sample file or screenshot can clarify things.
first of all thank you for your immediate response
i have Version: 2.1.3

i dont' know what fonts can i use to write greek words in Mtext menu i select greekc fonts and in
unicode window i select greek extended
i try to insert the greek word " ξενοφων " in greek fonts and the result is this in the picture
maybe i insert something wrong ?
I can't tell you the reason, but I have experimented a bit. I have found out I can write it by typing in, but the rhombs appear if I insert it (copied from your posting in greek letters) by pasting into the input box.
It might have to do something with the keyboard layout and mapping, or language setting in LibreCAD or your OS, but I am no guru on that.
I got some more success with greek_ol.
