New Comment:
There is no way to calculate base64, sha1 from unicode string
(unicode.script_encoding = UTF-8 [or UTF-16LE,UTF-16BE]) starting from
$unicode=chr(946)
because we don't have method to convert mutli-byte character sets to
it's binary representation
$unicode=chr(946)
When stript encoding UTF-8, chr(946)
base64($unicode) is zrI=
sha1($unicode) is 25b9b2c8a851851c7e0f1cff29a93a6aa6895f34
When stript encoding UTF-16LE, chr(946)
base64($unicode) is sgM=
sha1($unicode) is e84c936ce61a692fcc5a402b3b9b733592ba0b67
When stript encoding UTF-16BE, chr(946)
base64($unicode) is A7I=
sha1($unicode) is 2403f70ce33aeec4e21a519ffebb2864afc89fda

USE OLD PHP 5.x
// ---
valids values of UTF-16LE char(946) base64 / sha1
<?
print('UTF-16LE char(946):<br>');
print('base64: '.base64_encode(chr(178).chr(3)).'<br>');
print('sha1: '.sha1(chr(178).chr(3)).'<br>');
?>
// ---
valids values of UTF-16BE char(946) base64 / sha1

All examples above in utf-8
Imagine that using utf-16, sha1 and base64 will be not the same.

Please imagine that unicode chr(946) in binary have two bytes [11001110
10110010].

Example 4:
<?
print('You have to calculate sha1 of unicode chr(946)<br>');
print('regular sha1 of unicode chr(946) (\uceb2) is:
25b9b2c8a851851c7e0f1cff29a93a6aa6895f34'.'<br><br>');
$unicode=chr(946);
print(sha1((binary)$unicode));
print('<br>');
print(sha1(unicode_encode($unicode,'iso-8859-1')));
print('<br>');
// print(sha1(uni2bin($unicode))); //
25b9b2c8a851851c7e0f1cff29a93a6aa6895f34
?>
