FlexCelPdfExport.FallbackFonts Property
A semicolon (;) separated list of font names to try when a character is not found in the used font.
When a character is not found in a font, it will display as an empty square by default. By setting this property, FlexCel will try to find a font that supports this character in this list, and if found, use that font to render the character.
