# FontSet Object (IFontSet Interface)

This object provides access to the set of fonts to be used during document synthesis. FineReader Engine can work with both fonts registered in the system and fonts specified by the user. System and custom font sets have equal priority. You can use both of these sets together and additionally enable standard PDF fonts, if necessary.

To use fonts that support non-Latin characters, set the font families via CustomFontSet or SystemFontSet properties.* |
