Setting locale?

I have this thing I wrote called "Simple Contact Form." It's just a
straight-forward contact form. (Rather than repeat myself, check out
http://jimsun.linxnet.com/SCForm.html if you need to know more.)

I just received this email:

In the swedish alphabet we have three characters, å (an a
with a smal circle over it) ä ( an a with two spots ower it)
and ö ( an o with two spots over it). When I use the
emailform those chacters doesn't show as they should. Have
you any idea of what might be the cause of this?

Is this a problem with the locale not getting set?

In Perl, the thing to do is make sure to do a "use locale." But I
really haven't been able to find anything regarding a "standard
recommendation" for PHP.

From what I *have* found, it looks like what I want to do is
something like:

In the application's config file:

// Set this manually if the system default isn't the right thing
$locale = "";

In the code:

@setlocale(LC_ALL, $locale);

Is this right?

TIA,
Jim
