Hi, Olivier.

Yes, I noticed that.

The server has been set up and is maintained by myself, so I'm free to do any
modifications needed to solve the issue.

As for the headers, I tested them by using some online header-readers and saw
nothing unusual. If you see a page about browser compliance, there's a
screenshot available that prove the pages are correctly being rendered by a
number of browsers:

I have set up the HTTP Headers (on IIS/Win2k) so that it serves two different
ones:
1) UTF-8 for the forums root folder, otherwise the phpbb 3 messes up with
   accented characthers. This is working fine this way.
2) Windows-1252 (the same as in page's meta statements), for English/Portuguese
   pages on the web site.Also working fine.

I tested W3Cs validator with several by serving the pages with different
HTTP Headers (UTF-8, ISO-8859-1, etc) and also with none at all - nothing
works.

I am yet to try reading the headers from a Delphi program for wich I got the
source code - ICS from François Piette. I'm going to change one of its sample
projects so that it traces the read of server headers. I'll let you know if I
discover something weird (as the duplicate header you mentioned).

For now, thanks for replying so fast.
Very good this bug tracker!

Best regards,
Paulo França
