There are some consequenses that are not mentioned in the above
comments. More than one BOM renders a perfectly valid XHTM file
non-valid. Apparently the XHTML specification allows BOM characters,
but only ONE, not multiple which is what you get if you include other
utf-8 files (include, require). This in turn results in the possibility
that the xml declaration in not read since it is not found. This is the
case with the w3c validator.

That script appears to be written in UTF-16. As for UTF-16, it could
actually be a parser problem as well, but this report addresses the
issue related to UTF-8.

Actually, not totally. A friend mailed me a PHP script, which had the
annoying BOM AND the whole file was in double byte (saved by
notepad)... which definitely makes it a parser problem too (\0 < \0 ?
\0 p   doesn't match "<?p" for example).

And just for clarification, this is a scanner problem, irrelevant to
the parser.

It wasn't assigned, just set to open (and I didn't notice your name in
the "Assign to" field).

Derick,

Please do not change the status of the bug that is already assigned to
someone.

There's no point that PHP can only handle ASCII documents because if
you want to use German in PHP for example, at least you have to use
ISO-8859-1 or ISO-8859-15, which is not even part of ASCII.
