During import, LiveCycle Designer ES attempts to match fonts in the PDF file with fonts that are available on your computer. If the file contains an unavailable font, LiveCycle Designer ES displays the Missing Fonts dialog box showing the missing font and a suggested replacement. You can accept the replacement font or change it. This font substitution is not permanent. LiveCycle Designer ES must map the unavailable fonts every time the form opens.After importing the PDF, the Warnings tab of the Report palette lists all unavailable fonts and explains how they were converted. If the font-mapping table includes the unavailable font, the Warnings tab states that the font was mapped to the new font. If the unavailable font is not in the font-mapping table, LiveCycle Designer ES attempts to select an appropriate substitution. The Warnings tab then states that the unavailable font was changed to the new font. In this case, you may want to permanently substitute the font or add a new mapping to the font table.
