There is no option to save without the BOM in Windows Notepad. Nor is there an
option to save with/without the BOM in many other Windows editors. It is
automatically added to the file and there is nothing I can do about that --
short of writing a script to programmatically go through all my other scripts
with fopen(), remove the first three characters, and then re-save.
That is NOT a practical option. PHP should be handling this.
As it stands, PHP 5.4 is completely unusable. Until you guys fix this, I need
to
stick with 5.3, because 5.4 will break all of my scripts -- and all the scripts
of ANYONE who uses htmlentities() on a Windows server. Please take my
suggestion
about using the default_charset to heart. That would finally resolve this issue.

Save your document as UTF-8 *without* BOM. The  is just what the UTF-8
Byte Order Mark (BOM) looks like when it is output (which is probably something
you don't want, so save the file without it).

>From my command line:
php > echo htmlentities('©', ENT_COMPAT | ENT_HTML401, 'UTF-8');
©
it works fine. If you are actually providing the correct UTF-8 char it will
work
fine. You can verify that by doing this:
php > $a = chr(0xC2).chr(0xA9);
php > echo htmlentities($a, ENT_COMPAT | ENT_HTML401, 'UTF-8');
©
Here I am explicitly passing C2A9 in and I get © back out.
So I have no idea what your Windows Notepad is doing. Look at the output with a
hex editor and see what it is converting that copyright character to.

Yes, your assumptions about what I was meaning to say were correct. I really
meant "ANSI," which you know as CP-1252.
But there is definitely still a bug with this. I just followed your
instructions
by saving my test script specifically in the "UTF-8" encoding hoping that, as
you said, "all my problems will go away."
They didn't.
My test script is exactly the same one that I have listed on this bug report. I
saved it in Windows Notepad, using the "UTF-8" encoding. I am no longer getting
an empty string -- which is progress. But now I am getting the following output:
©
This is definitely NOT the expected result here. It did finally convert the
copyright symbol, but it prepended not one, not two, but THREE junk characters
in front of it. This is even worse than before.
If I'm not mistaken, wasn't the whole reason PHP6 was abandoned because the
idea
of converting everything to Unicode deemed too ambitious? I've already spent
far
too much time dealing with this than is practical, as I'm sure you have much
better things to do, as well. It just seems to me that you guys had a wonderful
hammer -- a wonderful tool for the job -- and you went and broke off the hammer
head for no apparent reason.
If I might make a humble suggestion, why not let htmlentities() default to
whatever the default_charset option is in php.ini? Right now you can only do
that by explicitly passing an empty string as the third parameter to
htmlentities, which is very messy and counterintuitive. Shouldn't the
default_charset actually be, you know, the _default character set_?

I think you are confusing CP-1252 with ISO-8859-1. And the default on Windows
internally is actually UTF-16 but there is a library call named isTextUnicode()
which most apps use to determine which encoding something is in and it tends
towards CP-1252 if it can't figure it out, so I assume that is what you mean
when you say everyone saves things in ISO-8859-1 on Windows. Every editor I
know
of has a very simple encoding setting to force the editor to a specific
encoding. Set it to UTF-8 and all your problems will go away. Note also that CP-
1252 is not used in most of the world, so this assertion that most pages are
saved in ISO-8859-1 is obviously not true. Regardless, this is not something
that will be reverted. CP-1252 is disappearing and I think you will find much
less of it in Windows8 as it really doesn't play well with HTML5.

With respect, the 72% figure you cited is misleading at best. The character
encoding listed in the HTML gives no indication of what encoding the files were
actually saved in. All it is is a <meta> tag in that <head> that says UTF-8. I
would suspect the vast majority of those files are still saved in ISO-8859-1,
though.
My prediction is that you're going to get A LOT of complaints over the switch
--
especially from Windows users, who almost always save things in ISO-8859-1,
since that is the default encoding in Windows. With PHP on Windows ever
growing,
fighting the Windows users is just shooting yourself in the foot.
