Javascript/PHP byte-order mark problem

Hi,

I have a PHP file which outputs javascript code. It works well in
Firefox, but Opera chokes on it.

The problem is the PHP file contains UTF characters, so when I output
javascript code with PHP echo, then PHP prepends the output with an
UTF BOM:

var data = <? echo "[...]" ?>;

results in

var data = <BOM>[...];

Opera doesn't like the BOM within javascript code, it indicates a
syntax error. I cannot save the PHP file as non-UTF, because other
parts of it have UTF characters.

Is there a workaround for this? Is there a way to prevent echo from
outputting a BOM when the page itself is UTF?

Here's the beginning of the data file:

00000000: 5b5b 5b22 3437 2e34 3935 3736 3022 2c22 [[["47.495760","
....


I'm at loss.

Are you looking at the real file, or some file that you uploaded? I seem
to remember some FTP clients abominable behaviour (aaargh, DON'T mess with
files)...

I've never seen PHP put in a BOM that wasn't actually there, so if it
isn't, I'm thorougly at a loss.

var data =

<efbbbf>undefined

Scary, isn't it? :)

I checked the PHP file again and it turned out the BOM was in the
file itself outside of the PHP section. I don't know any good reason
how it could get there, but it was there, so PHP was innocent.

Thanks for the help everyone and sorry for the noise. Anyway, this
thread may be helpful for someone who runs into the same problem
later.

for it's own good or to simple :P. I'd be highly tempted to check with a
possibly employed version control system when this was actually
introduced. Glad we have it solved, and there's not some weird bug in PHP
:).
