Display unicode symbols (heart, diamond, etc.) in FPDF

问题

I am currently using FPDF to generate PDFs in PHP. Occasionally, these PDFs must include unicode icons like hearts, diamonds, spades, etc. Here's an example:

"This is a string ♡♡"

However, I cannot get those symbols to display. I've tried mb_convert_encoding, iconv, changing the font and none of them are giving me the result I need. Chinese, Japanese and Korean text are all displaying without issue; the problem seems to be related only to symbols.

Any ideas of how to display these in FPDF? Thanks.

I'm using TCPDF for generating PDF files

 $UnicodeString='♡♡♡♡♡♡♡♡♡♡';
 $fileNameHere='UnicodeFile.pdf';

 $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
 $pdf->setFontSubsetting(true);
 $pdf->SetFont('dejavusans', '', 20, '', true);
 $pdf->AddPage();
 $pdf->writeHTMLCell(0, 0, '', '', $UnicodeString, 0, 1, 0, true, 'L', true);
 $pdf->Output($fileNameHere,'F');

I actually just ended up porting all the FPDF-dependent code to mPDF. Took a while, but ultimately better than trying to hack something together that works with FPDFs limited capabilities.

Thanks for the responses.
