And you're right -- it isn't a reasonable solution . Whatever is generating your characters should generating the same characters regardless. However, some word processing programs, like Word for example, make substitutions to those characters that look fine when reviewing the documents in Word, but when viewed by other programs don't look right. One of the most obvious and common ones for me is reviewing things like this: think thats another case I see this all the time in email where people use some key combination to produce an apostrophe when it translates to a comma. It would be nice if our applications would not make substitutions for us. This is similar to the PUNYCODE mess that some browsers make of IDNS. Only three percent of the Global population use English as their native language. The rest of the world wants on the Internet and wants to be able to use their own language. But some Browser developers (i.e., IE) don't want other-than-English characters to be shows in urls but instead show PUNYCODE, which was never designed to be viewed by the end user. Arrogance and ignorance are often coupled.

I guess I skimmed somewhat too ... but I based my assumption on the
following from the
OPs post:
/index.php/slides/upload:
$title = htmlentities($_POST['title'], ENT_COMPAT, 'UTF-8');
$image =
'/index.php/slides/preview?title='.urlencode($title).'&content='.urlencode($_POST['content']);
so the script handle the form submission looks to be generating a url
used as the src of an img.
Yes, the script generates an url to the script that renders the image.
$image is later used in an img-tag. Maybe there is another way to solve
this but this was the only thing I could think of.
I have noted that if I use numerical html entities for åäö (Å for
instance) I can see the characters correctly. I guess that would mean
the string passed is *not* correct utf-8.
Here is the current source:
$title = htmlentities( stripslashes($_POST['title']), ENT_NOQUOTES,
"utf-8" );
$content = htmlentities( stripslashes($_POST['content']), ENT_NOQUOTES,
"utf-8" );
$image =
'/index.php/slides/preview?title='.urlencode($title).'&content='.urlencode($content)."&align=$align";
...
$title = html_entity_decode(get('title'), ENT_NOQUOTES, 'UTF-8');
$im = imagecreatetruecolor(800, 600);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
//$font = "/usr/share/fonts/corefonts/arial.ttf";
$font = "/usr/share/fonts/ttf-bitstream-vera/Vera.ttf";
$title_size = 42;
imagefilledrectangle($im, 0, 0, 800, 600, $black);
$this->_string_centered($im, 70, $title_size, $font, $white, $title);
header("Content-Type: image/png");
imagepng($im);
Thus, it leads me back to my previous guess that the font he chose
(georgia.ttf) doesn't have Swedish characters in the set. With that,
I'm not sure, though, because I don't have the Georgia font pack on
here, so it'll have to stay as a guess for now.
Georgia.tff should cover swedish characters - atleast it does on my
system (MPB) ... my little test script in my other post on this thread
works for me ... I have no idea if one should/could expect variations
of supported characters in a TTF font file depending on the system your
on (my guess would be you could rely on all systems that have said TTF
file
to support the same chars - I assume that although it may be compiled
diffferently
for different platforms the source font definition is going to be the
same)
All fonts I have tried works in other applications with utf-8. (I run
lamp on my own workstation at the moment).
If anyone want to see the site or complete source I could send the url
off-list.

If you are 100% sure that the var $title contains a valid UTF-8
encoded text sting (simply output the string to the browser and set
the page encoding to UTF-8), then the only thing that is left that
might screw up the text-to-image output is the font you are using. As
you might know, you can only use TrueType fonts.
I am quite sure that the font supports the characters. I tried a couple
of fonts that I use in other programs with utf-8. I am, however, not
100% sure that $title is correct utf-8, but I think it is.

Page encoding would only come into play here if the data was written as an HTML string. Form elements generally don't give a damn how the rest of the page is configured, because their job is only to be a container to pass POST and GET data to the server (which, again, couldn't care less what the previous page's encoding was prior to receiving the new data). The only places it will matter in this case, and in order, are: 1.) The FORM element (properly configured) 2.) The browser's capability to send data encoded in the desired encoding (likely true with the OP) 3.) The server's ability to handle the encoding (again, properly configured, according to David) Thus, it leads me back to my previous guess that the font he chose (georgia.ttf) doesn't have Swedish characters in the set.
