Search term encoding problem

[phil@infomed.org]

Hi there,

We've been using zoom for a while. I just noticed a problem that I think was not there before.
Our website content is in German so there are many umlauts.

When we enter a search with a digraph there is no problem ... e.g. "Folsaeure" will show results for "Folsaeure" and "Folsäure".

However, when we enter "Folsäure" the search term gets "corrupted" to "Fols%C3%A4ure" and nothing is found. As far as I can tell the encoding is set properly on all the files. (we use the cgi version)

What am I missing?

Thanks

Here is the site ...

BTW, the site is here: www.infomed.ch

Any help is appreciated, thanks!

It seems like the result is returning OK from the CGI directly (note that it doesn't show up quite right because the template HTML doesn't specify UTF-8 charset, but if you change your browser encoding to UTF-8, it shows up correctly):
http://www.infomed.ch/cgi-bin/search.cgi?zoom_query=Folsäure

While the PHP script (infomed_search.php) that you are using to include the CGI output is re-encoding the parameter:
http://www.infomed.ch/infomed_search.php?zoom_query=Folsäure

If you are using the virtual() command already and doing something like described here, then your PHP might be configured to automatically encoding the parameters. Try adding a call to rawurldecode() like this:

<?php
$QSTRING = rawurldecode($_SERVER['QUERY_STRING']);
virtual("/cgi-bin/search.cgi".'?'.$QSTRING);
?>

Thank you Ray,

The rawurlencode helped.
Our hosting platform does not support virtual(), we had to replace it w/ :
echo file_get_contents('http://infomed.ch/cgi-bin/search.cgi?'.$QSTRING);

Everythings seems fine now though.

Thanks again
