Description:
------------
mbstring fails to match encoding name against any one of 
the supported encodings with some locale settings.

Irrelevant to bug #29955.

Reproduce code:
---------------
<?php
setlocale(LC_CTYPE, 'tr_TR.ISO-8859-1');

var_dump(mb_convert_encoding('abc', 'utf-8', 'iso-8859-1'));
var_dump(mb_convert_encoding('abc', 'UTF-8', 'ISO-8859-1'));

setlocale(LC_CTYPE, 'tr_TR.ISO-8859-9');

var_dump(mb_convert_encoding('abc', 'utf-8', 'iso-8859-1'));
var_dump(mb_convert_encoding('abc', 'UTF-8', 'ISO-8859-1'));
?>

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

Actual result:
--------------
string(1) "a"
string(1) "a"

Warning: mb_convert_encoding(): Illegal character 
encoding specified in %s on line %d
string(1) "a"
string(1) "a"

tr_TR == Turkish, and ISO-8859-1 is not a valid character set of that locale, no?

Right, there were typos. The reproduce code should've 
been

<?php
setlocale(LC_CTYPE, 'de_DE.ISO-8859-1');

var_dump(mb_convert_encoding('a', 'utf-8', 'iso-8859
-1'));
var_dump(mb_convert_encoding('a', 'UTF-8', 'ISO-8859
-1'));

setlocale(LC_CTYPE, 'tr_TR.ISO-8859-9');

var_dump(mb_convert_encoding('a', 'utf-8', 'iso-8859
-1'));
var_dump(mb_convert_encoding('a', 'UTF-8', 'ISO-8859
-1'));
?>

Rui, check this too if you don't mind. :)

mbstring (libmbfl) uses strcasecmp() which depends on the locale.
If the specified locale is not supported in the system,
encoding match fails.
It is not the problem of mbstring, but it is the problem of 
system setting.
