Bug description: binary representation of unicode
Description:
------------
converting binary<->string without charset translating for view binary
representation of unicode or generate unicode from valid binary consists
unicode sequenses
note that: unicode_encode/unicode_decode using charset translating, see
Reproduce code
Example 1:
You have (binary)$b. It consists two bytes: 11001110 10110010
Its length in binary representation is two.
It is also valid one-length UTF-8 char(946) (greek small letter beta)
How to conver it ($b) into one-char UTF-8 string??
When we try $u=(string)$b, it gives two-char UTF-8 string.
Example 2:
You have (string)$u UTF-8 one-char string. It consists chr(946) (greek
small letter beta)
Now You have to see two bytes binary representation of this (11001110
10110010).
There is no way to convert it without charset translation...
Reproduce code:
---------------
<?
$s=chr(946);
print(strlen($s));
print('<br>');
$b=unicode_encode($s,'iso-8859-1');
print(strlen($b));
?>
Expected result:
----------------
1 (unicode 1 char)
2 (binary 2 bytes) [11001110 10110010]
Actual result:
--------------
1
1
no way to converting binary<->string without charset translating
in binary we have length = 1 but it is 2 bytes
