Bug description: mb_check_encoding returns wrong result when using iso-2022-jp
character set
Description:
------------
The mb_check_encoding function returns false when a particular Japanese
character is used with the iso-2022-jp character set. The offending
character has hex code 2d6a. This is a special character representing
"incorporated". The character itself does not seem to be in the JIS X
0208-1983 character table, but most windows applications seem to recognize
it (Outlook, Firefox, Explorer, etc). In this particular case, the original
text was composed in Outlook.
Reproduce code:
---------------
//This is valid iso-2022-jp code for
//this single Japanese character representing incorporated
$txt = "\x1b\x24\x42\x2d\x6a";
//The output of the below code will be "bad encoding"
if(mb_check_encoding($txt,'ISO-2022-JP')){
echo 'good encoding';
}else{
echo 'bad encoding';
Expected result:
----------------
"good encoding" should be printed
Actual result:
--------------
"bad encoding" is printed
