Consider a shp file for a font with the following (among others) definition: *Diameter_Symbol,19, symbol 36 (diameter) 2,001,1,8,(16,54),2,8,(-8,-12),1,10,(15,020),2,8,(28,-42),0 This font properly works in AutoCAD, when I specify %%C in dimension text. However DraftSight when it opens the same file shows a Cyrillic letter ш instead of the diameter symbol.
