• Discretionary Ligatures don't work when you choose Kozuka Gothic Pr6N R or Kozuka Gothic Pr6N B font with Faux Italic or Faux Bold option turned ON in the Character panel.
• When you open document with Discretionary Ligatures, Photoshop displays a dialog prompting you to update the text layers. If you choose to update the text layer, the horizontal ligature turns into two glyphs and the vertical ligature is displayed as empty square (tofu box).
• Glyphs of Kozuka Gothic Pr6N R and Kozuka Gothic Pr6N B fonts are displayed incorrectly or displayed as empty square (tofu box) within the Libraries panel or when opened from the Libraries panel.
