I would like if you stick to the original issue: can a PHP source file be in
utf-8. It's not about the output, that is properly supported.
Think it would be a good idea anyhow that PHP would support utf-8 source
files as it seems utf-8 is going to be the de-facto standard for text files
anyhow.

Yes is the quick answer.
There's no better way than to try it yourself.

Do you mean ...
<?php
echo '早晨好';
?>
If you cut and paste that into your editor, make sure that the font
you are using is a UTF-8 font. Otherwise you will see the font's
unknown symbol glyph rather than the correct ones.
If your font doesn't have the symbols, it doesn't affect the code. The
editor is only displaying the code. It doesn't alter the code.
Richard.

Bob wrtote:
The real question is whether unicode is even relevant now that the UTF
series is available.
Ashley answered:
Bob, UTF is unicode (Unicode Transformation Format)
Yes, Ashley is correct. UTF-8 is Unicode, as is UTF-16 and UTF-32,
which all use different a number of bytes for each code point. Both
UTF-8 and UTF-16 are variable length whereas UTF-32 is a fixed length
of four bytes per code point.
As is my understanding, UTF-8 will accommodate all the languages
(glyphs) of the world and then some. It will be a while before we
need UTF-16 or UTF-32 but those are just a larger super-sets.
In any event, I always use UTF-8 in all my encoding.
Cheers,
tedd

Ash:
Try it again (it worked for me).
In any event, the link was supposed to be redirected to this site:
http://xn--fci.com
If you run Safari, then the url will be shown as a check-mark.
My most popular IDNS site is square-root dot com (option v):
http://xn--19g.com
The story about that site is on the web page -- you may read if interested.
The site receives over 150 unique Mac visitors per day and that
number keeps climbing -- I don't know why. For example, one day I had
over 800 visitors from Spain -- why???
Obviously, I'm trying to sell the domain (for 6 figures), but have
had no takers.
I can always get back into Macintosh software development and use the
site to sell my own apps -- that's an option I ponder whenever my
clients don't call me for a week.
Who knows what may happen.
Cheers,
tedd
PS: I have over a dozen IDNS domains including the Pharmaceutical
Icon, Yin-Yang Symbol, Sigma, Delta, and DOT dot com (option 8).

Note, what I provided here does not include anything on the ajax.
Hope this answers your question.
Alice :
I didn't have a question, but here's my revision of your code:
http://www.webbytedd.com/cccc/alice1/
Please review the code and see how: 1) I captured the select value;
2) and how I used that value to focus the selected option.
You say:
Note, what I provided here does not include anything on the ajax.
I've never put anything "on the ajax" -- that doesn't make sense.
Ajax is simply a way to communicate from the browser to the server
and back again without requiring a browser refresh. As the user
triggers a client-side event (i.e., click, select, enter text, move a
mouse, whatever), a javascript routine then sends data to the server
to activate a server-side script, which may, or may not, return data.
For example -- with javascript turned ON please review:
http://www.webbytedd.com/a/ajax-site/
This is simply a one page template that uses an ajax routine to
retrieve data from the server to populate the page based upon what
the user triggers (i.e., the visitor clicks a navigational link).
If you will review the HTML source code, you will find a very basic
HTML template that will remain static for all three "apparent" pages.
If you use the FireFox browser you can review the generated HTML.
Now where did the generated HTML come from, you might ask? It came
from the server after a request was made from the client to the
server and the server responded with the correct data -- all without
requiring a browser refresh. That's an example of how ajax works.
Keep in mind that using "best practices" requires you to *first*
design forms to collect data WITHOUT requiring javascript and then
you can enhance the form to provide additional functionality to those
who have javascript turned on. Also keep in mind that you may not
need ajax to alter the form. You only need ajax if there is data on
the server that needs to be retrieved.
Now, please turn javascript OFF in your browser and review my page again:
http://www.webbytedd.com/a/ajax-site/
That's an example of NOT following "best practices". The visitor is
provided nothing if they have javascript turned OFF.
Now considering such, what additional functionality do you want your
form to do that can't be done already?
Cheers,
tedd
