Bug description: mb_ereg_replace() and preg_replace() is not caseinsensitive
for multibyte
Description:
------------
The function mb_eregi_replace() and/or function mb_ereg_replace() with
'i' option is not caseinsensitive for multibyte characters.
The same problem occurs for preg_replace() with /i option.
This bug was reported before twice:
1) (#39999) and was marked as Bogus stating it's not php bug.
2) (#25953) was marked as Won't fix with note "Probably the issue will
be resolved in php5."
As one cannot add anything to closed bug I'd like to reopen this bug here
for the reason stated below:
This library is not linked dynamically, on contrary its source is present
in php source repository. So there's no way for php users to have this
problem fixed without php itself being fixed.
More than that, the version of oniguruma in php repository is pretty old
so at least importing the newer version of it would be a nice try to fix
this bug.
Reproduce code:
---------------
<?
mb_internal_encoding('UTF-8');
mb_regex_encoding('UTF-8');
$pattern = ''; //s 'crown'
$replace = 'X';
$subject = 'iltas, iltas';
$result = mb_eregi_replace($pattern, $replace, $subject);
echo $result;
$result = preg_replace("/$pattern/iu", $replace, $subject);
echo $result . "\n";
?>
Expected result:
----------------
Xiltas, Xiltas
Xiltas, Xiltas
Actual result:
--------------
iltas, Xiltas
iltas, Xiltas
