Description:
------------
The warning message is only generated when display_errors = off

Tested using Apache 2.2.13 (win32)

Reproduce code:
---------------
echo htmlspecialchars(chr(224), ENT_COMPAT, 'utf-8');

Expected result:
----------------
PHP Warning:  htmlentities(): Invalid multibyte sequence in argument in [...] on line [...]

Actual result:
--------------
display_errors = Off   ->   The error message is logged but not displayed (correct)
display_errors = On    ->   No error message is neither displayed nor logged (buggy?)

Obviously assuming log_errors = On.

With a custom error handler and display_errors = off the handler is called and the error informations are correct.

If display_errors = on the custom error handler isn't called.

See bug #47494 and my comment there for reason. Another reason for this to be bogus: you failed to search before submitting another report about same issue.

Sorry for double submission, I've searched for a similar bug but haven't found it.

I read your comment on the other bug entry and checked out source code, but i don't get the point to make it intentional. We have to retest our whole code with display_errors=off in order to check for errors that otherwise won't be displayed? :S

Anyway thank you for your response. :)
