Summary: strlen result wrong after passing through
html_entity_decode
-Status: Open
+Status: Not a bug
Type: Bug
Package: Unknown/Other Function
Operating System: Windows 7
PHP Version: 5.4.16

New Comment:
html_entity_decode(' ') returns a U+00A0 NO-BREAK SPACE, which encoded in
UTF8 is "\xc2\xa0". strlen() returns the length in bytes (not code points), as
such strlen("\xc2\xa0") will be 2, not 1.
If you want to have the output in a different encoding (e.g. ISO-8859-1) you
can specify it via the last argument to the function.

Description:
------------
If you run string "X X" through html_entity_decode then check its' length
it returns 4 instead of 3.
PHP 5.3.x gives correct result.
PHP 5.4.x and 5.5.x give incorrect result.
Possibly the same problem with other HTML entities, such as » etc...
Test script:
---------------
<?php
echo 'strlen(a) = ' .strlen("X X") . "<br>\n";
echo 'strlen(b) = ' .strlen(html_entity_decode('X X')) . "<br>\n";
?>
Expected result:
----------------
strlen(a) = 3
strlen(b) = 3
Actual result:
--------------
strlen(a) = 3
strlen(b) = 4
