i think it's not a bug, just something like #62351.
set
mbstring.internal_encoding = utf-8
in php.ini, and then everything works fine.

Description:
------------
Take the test script below and save it as UTF-8 and verify:
> cat test.php | tail -n 4 | head -n 1 | hexdump -C
00000000 09 23 20 c3 a4 c3 b6 0a |.# .....|
00000008
Now run
> ./bin/php test.php | hexdump -C
PHP Version = 5.4.8
zend.multibyte = 1
00000000 58 00 00 00 |X...|
00000004
As you can see PHP added three NUL bytes to the file.
Now remove one of the characters in the commented out line:
> ./bin/php test.php | hexdump -C
PHP Version = 5.4.8
zend.multibyte = 1
00000000 58 00 00 |X..|
00000003
As you can see the NUL bytes are directly related to the amount of non-ASCII characters in the file.
Now comment out the declare statement:
> ./bin/php test.php | hexdump -C
PHP Version = 5.4.8
zend.multibyte = 1
00000000 58 |X|
00000001
This time the output is correct.
Tested with off-the-shelf PHP, but also happens with ubuntu packaged 5.4.6-1
Also happends when PHP is running as Apache module where this issue caused corrupted images for me.
Test script:
---------------
<?php
declare(encoding='UTF-8');
fwrite(STDERR,"PHP Version = ".phpversion()."\n");
fwrite(STDERR,"zend.multibyte = ".ini_get('zend.multibyte')."\n");
# äöü
echo "X";
?>
Expected result:
----------------
See above.
UTF-8 declared files with UTF-8 content should work fine.
Actual result:
--------------
See above.
UTF-8 declared files with UTF-8 content produce NUL bytes in the output.
