Hello,
thank you for the answer.
I thought it is utf-8, because the function mb_detect_encoding gives
utf-8.
After your answer i testet it with
function is_utf8($string) {
// From http://w3.org/International/questions/qa-forms-utf-8.html
return preg_match('%^(?:
[\x09\x0A\x0D\x20-\x7E] # ASCII
| [\xC2-\xDF][\x80-\xBF] # non-overlong 2-byte
| \xE0[\xA0-\xBF][\x80-\xBF] # excluding overlongs
| [\xE1-\xEC\xEE\xEF][\x80-\xBF]{2} # straight 3-byte
| \xED[\x80-\x9F][\x80-\xBF] # excluding surrogates
| \xF0[\x90-\xBF][\x80-\xBF]{2} # planes 1-3
| [\xF1-\xF3][\x80-\xBF]{3} # planes 4-15
| \xF4[\x80-\x8F][\x80-\xBF]{2} # plane 16
)*$%xs', $string);
}
and this gives 0, also not utf-8. :-(
I quickly made this test:
I use char("äüö") it gives 228 which is correct ISO... "ä",
then utf8_encode("äüö") and testing with the function is_utf8 gives 1,
also the string seems now to be utf-8 encoded.
If i now send this converted string to "imagettftext" the result is
again one square and ö.
Possibly i made something wrong, because i am not an php programmer.
But for me it seems, that the code of two characters become one utf-8
character.
I am making more tests next days an then i tell the results.
If someone can tell some futher tests, i will do them an post the
results.

Do you use UTF-8? Text has to be given in UTF-8. If not, it may cause
some troubles by the encoding detection or the glyph selection in
freetype (esp. when the font only has utf-8).

Description:
------------
want to put special characters (german umlauts) into an image.
I use imagettftext() and the string "( ä ü ö xx Ä Ü Ö ß ) without
blanks ( äüöxxÄÜÖß )".
If i put an blank around the characters it works without blanks there
squares.
You see the result on:
http://heisenberg.rmroppert.com/test/gd_php_out.pdf
I tried the same on different machines (i386) under different NETBSD
Versions (NetBSD 1.6, NetBSD 3.0.1, NetBSD 3.1)
and different php versions.
You may find the output of phpinfo of our testserver under:
http://heisenberg.rmroppert.com/test/phpinfo1.pdf
I think this is an problem of th built-in version og gd. Perhaps the
image is correct if i use perl and gnuplot.
Reproduce code:
---------------
<?php
$argtext=" ( ä ü ö xx Ä Ü Ö ß ) without blanks ( äüöÄÜÖß ) ";
$font1="/usr/pkg/share/httpd/htdocs/testphp/test/Arial.ttf";
$im = imagecreate (1810, 100);
$white = imagecolorallocate ($im, 255, 255, 255);
$black = imagecolorallocate ($im, 0, 0, 0);
imagefilledrectangle($im,0,0,609,99,$white);
imagettftext ($im, 30, 0, 10, 40, $black, $font1, $argtxt);
header ("Content-type: image/png");
imagejpeg($im);
imagedestroy($im);
?>
Expected result:
