Hi, I've ran into some problems when outputing text to an image using
imagettftext. I cannot get swedish characters to work, I just get a
square. I've tried different fonts which I know has those characters
(bitstream vera, arial, times new roman, etc). What am I doing wrong?
Most likely, it's because the font doesn't have an entry for those
characters. Try to find a TTF font that does have those entities and
your problems will most likely be solved that easily.

I know I must pass utf-8 encoded text and I belive I do but I don't know
how to check it.
HTML form code:
(html document uses utf-8 as charset and apache is set to use utf-8 too)
form action=/index.php/slides/upload method=post
accept-charset=utf-8
input type=text id=title name=title size=70 value= /
/form
/index.php/slides/upload:
$title = htmlentities($_POST['title'], ENT_COMPAT, 'UTF-8');
$image =
'/index.php/slides/preview?title='.urlencode($title).'content='.urlencode($_POST['content']);
/index.php/slides/preview:
function preview(){
$title = html_entity_decode($_GET['title'], ENT_COMPAT, 'UTF-8');
//$title = $_GET['title'];
///@note Hardcoded resolution
$im = imagecreatetruecolor(800, 600);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
$font = /usr/share/fonts/corefonts/georgia.ttf;
$title_size = 32;
imagefilledrectangle($im, 0, 0, 800, 600, $black);
imagettftext( $im, $title_size, 0, 50, 50, $white, $font, $title );
header(Content-Type: image/png);
imagepng($im);
exit();
}
have you tried a test script (file encoded as UTF8) where you hardcode the
title string and see if that also outputs 'squares' ... at least that way
you can be sure whether the problem is in some kind of encoding mush that occurs
during the title's roundtrip of server - browser - server OR whether the
problem is
actually to do with imagetfftext.

I tried in on my local machine (php5.2.5) and I can output swedish characters
no problem (I hope the below test script comes through with borking the
UTF-8 chars)
?php
set_time_limit(0);
//$title = html_entity_decode($_GET['title'], ENT_COMPAT, 'UTF-8');
//$title = ' bork';
//$title = 'Pippi Långstrump går om bord';
/*
$title = 'Alla människor är födda fria
och lika i värde och rättigheter.
De är utrustade med förnuft och
samvete och bör handla gentemot
varandra i en anda av broderskap.';
//*/
$title = 'hå kå Å å Ä ä Ö ö å ö';
///@note Hardcoded resolution
$im = imagecreatetruecolor(400, 200);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
//$font = /Applications/OpenOffice.org
2.3.app/Contents/share/fonts/truetype/Georgia.ttf;
