Create Fallback Font

Aspose.Slides supports IFontFallBackRule interface and FontFallBackRule class to specify the rules to apply a fallback font. FontFallBackRule class represents an association between the specified Unicode range, used for searching missed glyphs, and a list of fonts that may contain proper glyphs:

uint startUnicodeIndex = 0x0B80;
uint endUnicodeIndex = 0x0BFF;

IFontFallBackRule firstRule = new FontFallBackRule(startUnicodeIndex, endUnicodeIndex, "Vijaya");
IFontFallBackRule secondRule = new FontFallBackRule(0x3040, 0x309F, "MS Mincho, MS Gothic");


//Using multiple ways you can add fonts list:
string[] fontNames = new string[] { "Segoe UI Emoji, Segoe UI Symbol", "Arial" };

IFontFallBackRule thirdRule = new FontFallBackRule(0x1F300, 0x1F64F, fontNames);

It is also possible to Remove() fallback font or AddFallBackFonts() into existing FontFallBackRule object.

FontFallBackRulesCollection can be used to organize a list of FontFallBackRule objects, when there is a need to specify fallback font replacement rules for multiple Unicode ranges.
