Gets or sets a value that determines whether custom glyph forms can be used based upon the context of the text being rendered.
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.
Random contextual alternates provide multiple substitute glyphs for a single character. When implemented with script-type fonts, this feature can simulate handwriting by using of a set of randomly chosen glyphs with slight differences in appearance.
