I have a pdf which contains 'UniCNS-UCS2-H' font, I tried both pdfbox and pdfrenderer, they all throw exception: Unknown encoding for 'UniCNS-UCS2-H'
and this font was included in a font file :mingliu.ttc(it's a true type collection file, I don't know does this matter ?
what can I do to let these two libraries support additional fonts ?
