Re: [PHP-DEV] mbstring internal encoding behavior

Hello,

Redirecting to php-i18n list, which is the most suitable place

So you set the internal encoding to UTF-8 while having translated
message catalog as Shift_JIS. Then which encoding are you using
primarily in your script? And is there any reason not to use UTF-8
everywhere applicable?

What settings did you put in your php.ini about mbstring?
Does it contain any part like "mbstring.language" comes after 
"mbstring.internal_encoding"?

Which encoding is used for the input data?
