如何使用Unicode Bangla字符生成PDF?

I am facing a problem with generating reports in PDF format with PHP. I have tried the FPDF, TCPDF, and HTML2PDF libraries but they do not support all Unicode Character sets.

TCPDF supports Czech (cz), Danish (da), German (de), Spanish (es) etc. But I need to output both English and Bangla text. But the Bangla characters are being replacing with ?s.

Is there a PHP library which supports all Unicode Character sets? How I can output Bangla charater sets with FPDF, TCPDF, or HTML2PDF?

FPDF has support. Please check out this: http://www.fpdf.org/phorum/read.php?f=1&i=5142&t=5142
