Gets or sets a value that indicates whether a stylistic set of a font form is enabled.
Assembly: System.Windows (in System.Windows.dll)
This property gets or sets a value on the object that owns a Typography property, which is the only way to access a Typography class instance. In addition, this property supports an attached property usage so that it can be set on text-containing objects in XAML.
Some fonts contain stylistic variant glyphs that correspond to portions of a character set. Glyphs in stylistic sets may be designed to harmonize visually, interact in particular ways, or work together in other ways.
