Hello I have prepared a pdf by using TCPDF, but I have a problem regarding printing tick instead of 'GREEN X'. I am using html decimal value (✔), but it always shows question mark(?).
Image of structure is here https://i.stack.imgur.com/us4EN.jpg
My code of printing marks 'X' and 'O' is
$color = $pdf_colour[$row];
$this->SetTextColor($color[0],$color[1],$color[2]); // where color contains value of RGB
$text = $colour_text[$row]; // where $colour_text[$row] contains symbols ie, X,O
$this->Cell(self::w,0,$text, '', 0, 'L', $fill);
Please advice thanks.
