PHP GD not rendering unicode fonts properly

I开发者_Go百科 am having problems in rendering unicode glyphs ( language : Malayalam, Tamil and Hindi) with PHP GD library. Is this something related to the rendering engine of GD library? Any workarounds available ?

First make sure your fonts contain the desired glyphs (system fonts such as Arial should). Then make sure you convert your parameters to unicode using utf8_decode() if neccessary.

i have found one try this

<?php
//error_reporting(0);
$text = ("Unreadable text");
$font = "mangal.ttf";
$fontSize = "10";
$width = '600';
    $s = new CairoImageSurface(CairoFormat::ARGB32, $width, 21);
    $c = new CairoContext($s);

    /* Set the background*/
    $c->setSourceRGB(.1,149,.58);
    $c->paint();

    $c->setSourceRGB(.1,.1,.1);

    /* Make a Pango layout, set the font, then set the layout size */
    $l = new PangoLayout($c);
    $desc = new PangoFontDescription("mangal normal $fontSize");
    $l->setFontDescription($desc);

    /* Here, we use Pango markup to make part of the text bold */
    $l->setText($text);

    /* Draw the layout on the surface */
    $l->showLayout($c);
    $s->writeToPng("unicode.png");
    echo $img = "<img src=\"unicode.png\">";        
?>
