Property Value

true if standard ligatures are enabled; otherwise, false. The default value is true.

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.

The following text displays standard ligature glyphs for the Pericles font.

Example of standard set of ligatures

Text using OpenType standard ligatures

The following code example shows how to define standard ligature glyphs for the Pericles font, using the StandardLigatures property.

<Paragraph FontFamily="Pericles" Typography.StandardLigatures="True">
  <Run Typography.StylisticAlternates="1">FI</Run>
  <Run Typography.StylisticAlternates="1">FL</Run>
  <Run Typography.StylisticAlternates="1">TH</Run>
  <Run Typography.StylisticAlternates="1">TT</Run>
  <Run Typography.StylisticAlternates="1">TV</Run>
  <Run Typography.StylisticAlternates="1">TW</Run>
  <Run Typography.StylisticAlternates="1">TY</Run>
  <Run Typography.StylisticAlternates="1">VT</Run>
  <Run Typography.StylisticAlternates="1">WT</Run>
  <Run Typography.StylisticAlternates="1">YT</Run>
</Paragraph>

By default, OpenTypes fonts in WPF enable standard ligatures. For example, if you use the Palatino Linotype font, the standard ligatures "fi", "ff", and "fl" appear as a combined character glyph. Notice that the pair of characters for each standard ligature touch each other.

Example of standard ligatures enabled by default

Text using OpenType standard ligatures

However, you can disable standard ligature features so that a standard ligature such as "ff" displays as two separate glyphs, rather than as a combined character glyph.

Example of disabled standard ligatures

Text using disabled OpenType standard ligatures

The following code example shows how to disable standard ligature glyphs for the Palatino Linotype font, using the StandardLigatures property.

<!-- Set standard ligatures to false in order to disable feature. -->
<Paragraph Typography.StandardLigatures="False" FontFamily="Palatino Linotype" FontSize="72">
  fi ff fl
</Paragraph>

If the value of StandardLigatures is true and the selected font does not support standard ligatures, the default form of the letter is displayed.
