Hi Harvey,
Thank You for your response.
Firefox does not load anything but just the weird characters.
They are a sequence of inverse interrogation marks, quotes etc.
They appear at default page loading.
In fact when I edit the source file, there is a line at the
top of the file and nothing else. I deleted the line, saved the
file and uploaded it to the web server with Filezilla.
When I edit the uploaded file the line at the top appears
again and the pb also.
I therferore suspect that the intrusive characters are
inserted during the upload.
I have checked the Filezilla parameters to force a binary
copy and characters to UTF-8.
Without any success....
Here we are, still needing a solution.
Anyway, thanks for your help.
Regards
