The switch clause is needed so that illegal multibyte occurrences would
be detected per specification. I'm going to look into this one.

the patch removes a strange 'switch (errno)' that I don't really know
why it was there and adds a check for _php_iconv_appendl()

Of course, title is: iconv_substr() gives "Unknown error" when string
length = 1" 

Operating system: Windows XP.

It is not my error - bugs.php.net has bugs!

Description:
------------
(Similar to bug #34757).

When input string length = 1, iconv_substr() produces "Unknown error
(0)" and returns FALSE.

Reproduce code:
---------------
$s = 'x';
$s = iconv_substr($s, 0, 1, 'UTF-8');

var_dump($s);

Expected result:
----------------
string(1) "x"



Actual result:
--------------
bool(false)


and Notice: iconv_substr() [function.iconv-substr.html]: Unknown error
(0) in ...
