Summary: mb_strtoupper fails on Japanese characters
Status: Feedback
Type: Bug
Package: mbstring related
Operating System: Windows Vista
PHP Version: 5.2.11

Description:
-----------
I actually just encountered this problem as well with ucfirst() but not
mb_strtoupper(). I would not even comment except that PHP 5.3.8 fails on using
ucfirst() whereas 5.3.6 succeeds. As such, my code that had worked previously
had stopped working before I put in a workaround using mb_strtoupper().
I do not know if PHP considers this to be a problem or not, since technically
the software writer should not have used ucfirst() to begin with. However, it
seems like a problem to me when an ostensibly minor update has the result of
unnecessarily breaking code.
It did not work properly on two system I used, and did work properly on one
system. Systems I tried:
*did NOT work - PHP 5.3.8 (cli) (built: Aug 23 2011 12:14:39)
*did NOT work - PHP 5.3.8 (cli) (built: Nov 8 2011 22:18:15) (custom build,
IIRC)
*worked properly - PHP 5.3.6-13ubuntu3.2 with Suhosin-Patch (cli) (built: Oct
13 2011 23:09:42)
Reproduce code:
---------------
echo
ucfirst(urldecode("%E6%97%A5%E5%85%89%E6%9D%B1%E7%85%A7%E5%AE%AE%E9%99%BD%E6%98%8E%E9%96%80"));
Expected result:

Result given in failing versions above:

mbstring.func_overload = 0. Setting it to 2 or 7 just means there is
no difference between calling sttrtoupper() and mb_strtoupper(), but
ucfirst() still produces incorrectly coded strings. This is using UTF-
8 for internal encoding. Using UTF-16 and UTF-32 basically crashes the
program.
mbstring.strict_detection = Off. Setting it to On does have no effect
whatsoever. I.e. if I check with phpinfo() it stays off, no matter
what I specify as value. This is not the case with other php.ini
settings. Besides there is no documentation on its effect.
I really researched this problem - but cannot not show you because
then this form says I am spammming - but the crux of this problem is
that UTF-8, UTF-16 and UTF-32 each behave differently when used with
strtoupper() and mb_strtoupper() and all can result in string that are
not valid encodings.
I have a working solution for my case, but I think this is a solvable
bug.

Please read this page and especially the last two examples:
http://www.php.net/manual/en/mbstring.configuration.php
Are you using the proper options?
