I downloaded the ominous html page, coded it as UTF-8 (with text-editor option)
and added a metag-tag declaring utf-8 encoding:
<meta http-equiv = 'content-type' content = 'text/html; charset=UTF-8'>
I checked that the special characters were written correctly then (actually I had to correct them).
Then I used the function:
$doc = new DomDocument('1.0', 'UTF-8');
The result is still the same, special chars are displayed wrong. Different wrong than before :-)
but still wrong... ("ä" is now "ä").
I tried analogy to do the same with "ISO-8859-1" but it's not getting better...
So, fazit, even converting the whole document in UTF-8 and adding UTF-8 charset
declaration to it, doesn't help me handling special chars...
And what about the img-tags which are converted into what ever invisible chars
(empty spaces looking at the source code)...?
Do you have your code somewhere?
Another thing I realized that I failed to mention before is that
using saveXML($element) will serialize the full element, but outputs it
in UTF-8 encoding. Have you tried converting the output of that to the
encoding of the original HTML page?

Hello Rob,
> Do you have your code somewhere?
Yes, I paste it below. There are two files, one for HTML output (which I make
invisible with style declaration "display:none;" and the second file is a
javascript function which is supposed to output the content...

Well, I don't know any charset converting function which would be from standard
library...
Here are the two files...
Thank you for your time...

Try this line:
$this->ticker .= utf8_decode($child_elements->item($j)->textContent);
Your original HTML document is ISO-8859-1, so when you want the text I
think you want to convert the UTF-8 (Internally DOM document works with
UTF-8) to ISO-8859-1. Just using the utf8_decode function here from
ext/xml. This elminates those  characters you were getting.

I looked all through the documentation but was unable to find out if this
was possible and, if so, how. When you call ->saveXML(), it prints out the
XML declaration <?xml version="1.0"?> alont with the structure of the
document. Is there any way to suppress that? I'm trying to print out extra
text (in the form of a stylesheet call) and the declaration that ->saveXML()
prints out is messing everything up.
Would it be possible to point to the relevant page in the documentation that
discusses how to do this?
thnx,
Chris
