I don't know iif this is what you want but here we go: Open the drawing and select the Format pull down menu, then open Text Style and within that dialog box check out the Font Name box for the font that you desire.
Anotherway to check out for the Font listing, go to window explorer, select the drive (in my case it is C)in which you have program files, then select the ACAD folder and check out the fonts file.
