> What is the best way to find a suitable font ?
> I assume that PDFont cannot load directly a java.awt.Font.
> But I want to parse a PDF and find a text occurrence using "TextPosition textStart;"
> A this moment I can retrieve the good font using  :
> 		float fontSize = textStart.getFontSize();
> 		PDFont font = textStart.getFont();
> But in the PDF, the font is not complete (partial incorporated font).
> So If I want to replace "#date#" by  "10 Novembre 2015", i can have this result  "1? Novembre 2?1?". Because "0" is not present in the "partial incorporated font"
> So I need to determine the font used and find on the server the TTF font source, and then load it using .
> I found on forums this thread http://stackoverflow.com/questions/13077611/how-to-retrieve-the-native-font-name-in-java
> Then I wrote this source code to "do the job"
> {code}
