[iText-questions] Cannot see characters in PDF if wingding is embedded.

[B J]

Hi,

 

I use iText to generate PDF documents and it works great for me, but I face the following problem when I generate PDF with wingding font embedded inside it.

 

When I render characters that wingding can display (java.awt.font.canDisplay(char)) on a JFrame, I can correctly see the symbols. But if I generate PDF and then open it in Acrobat it displays rectangles (represenging non-printable characters, I guess). The same is the case with xpdf viewer(linux).

 

The code listed at the end of this mail first displays the characters on JFrame, when window is closed it generates the document with wingding embedded inside it (note that I do set its encoding to cp1252 as required).

 

Could you please give me some hint on why is this happening or is this at all a problem of PDF document generation.

 

Thanks,

 

Bharat.
