title: Does one need to have a license for fonts if we are using ttf files in itext?
body: <p>I understand that itext does not come with any of the font libraries and you need to provide the font library . 
  The pdf once generated, will be viewed by Acrobat and assuming , it is the standard fonts, adobe would have support for it.
  My questions is about licensing of the fonts. </p>
  
  <p>a) Do I need to have a license of the fonts which I am using in iText ? For eg if I am using Arial, one of the most commonly used font and which is not free, do I need to purchase the font ?</p>
  
  <p>b) If I using any specific font for eg STSONG.ttf , for Chinese characters, do I need to have a license for this ?</p>
