Description:
------------
Attempting to display UTF-8 content in a Windows console (having used chcp 65001 to allow UTF-8 content to be displayed)

2 issues are found.

1 - php -r does not read UTF-8 from the commandline.

php -r "echo 'página';"

fails with

p�gina


2 - echo-ing utf-8 content adds an extra line.

Running the script ...

<?php echo echo 'página';

outputs página correctly, but with an extra line on the display.

But, if you capture the output, there is no extra line, which suggests to me that PHP is calling a function that outputs the extra line in some way.

Test script:
---------------
This is a batch file that demonstrates that UTF-8 output is possible in some circumstances.

Expected result:
----------------
Lots of ...

Actual result:

Some ...

but also ...

====== Via php -r

====== Via php -r, captured to a log file and displayed
p�gina

====== From a php script
página

I typo-ed an extra 'echo' in my bug report ...

The php script should be ...

<?php echo 'página';

And bug 3:

Added var_dump() to the PHP mix.

In a PHP script, the var_dump() is WAY wrong!!! 7 characters (yay) but with an extra 'a' at the end!

But if output capture is being performed, then the output is correct. No extra 'a' !

I've updated the gist to properly enforce utf8 mode in the console - https://gist.github.com/RQuadling/068ac672d97e2e3e6cfa

I realised that I was already in codepage 65001. This didn't affect the bugs I am reporting.

More updates. And added a pipe through cywgin's hexdump to see what comes out of PHP. Seems the captured output is fine, but uncaptured, ... seems PHP is behaving differently in some way.
