Thanks for more info. Yeah, i guess the issue is that we the A versions of the API are used. Getting
a VM with Chinese simplified to check more.
Thanks.

if php uses SetEnvironmentVariableA now, it can convert UTF8 to UTF16 and use
SetEnvironmentVariableW.
I don't know if this is a solution of this problem.

Oh, if I change the encoding of the test script from UTF-8 to GBK (from 3 bytes per char to 2 bytes
per char), it will be OK.
I don't know if there is any settings wrong with my Windows (Chinese simplyfied version). It
seems that the system only accept non-ASCII char in 2 bytes (in another word, system use GBK
encoding). System accept & return the value in GBK encoding, but php pass & retrieve env var
in UTF-8 encoding.
I set an Environment variable in control panel, and retrieve the value in php by getenv. I got an
GBK encoding byte string cannot read. Because php7 use UTF-8 as default ouput encoding. I tried
echo iconv('GBK', 'UTF-8', getenv('FOO'));
and got the expected value.
I think this bug may be the limitation of Windows platform, and may not be fixed unless Windows
change the its default encoding to Unicode.
Thanks.
Another test script:
---------------
// Greek_alphabet 'α' === urldecode('%CE%B1')
var_dump(putenv('FOO=α')); // true
php.ini:
---------------
; PHP's default character set is set to UTF-8.
; http://php.net/default-charset
default_charset = "UTF-8"
; PHP internal character encoding is set to empty.
; If empty, default_charset is used.
; http://php.net/internal-encoding
;internal_encoding =

Ah, and the encoding of the file you've posted, too.
Thanks.
