Edit report at https://bugs.php.net/bug.php?id=65110&edit=1 ID: 65110 Updated by: nikic@php.net Reported by: f133715 at rmqkr dot net Summary: mb_convert_encoding's auto is not work, when using mbstring.language=English -Status: Assigned +Status: Open -Type: Bug +Type: Documentation Problem Package: mbstring related Operating System: Windows PHP Version: 5.4.16 -Assigned To: moriyoshi +Assigned To: Block user comment: N Private report: N New Comment: Quoting from http://php.net/manual/en/mbstring.supported-encodings.php: > If "auto" is set, it is expanded to the list of encodings defined per the NLS. > > For instance, if the NLS is set to Japanese, the value is assumed to be > "ASCII,JIS,UTF-8,EUC-JP,SJIS". The default detection order that "auto" expands to depends on the language. The list you quoted is for Japanese. For English it only consists of ASCII and UTF-8. It would be good if the documentation mentioned what the actual detection orders are for the supported languages. Previous Comments: ------------------------------------------------------------------------ [2013-06-24 12:44:21] f133715 at rmqkr dot net Description: ------------ 1. The version number of the PHP package or files you are using. Latest PHP 5.4 for Windows 2. A short script that reproduces the problem <test script> Sometimes, it produce this error on log file: Warning: mb_convert_encoding(): Unable to detect character encoding in XXX.php on line XXX It seems that 'auto' is not expanding to "ASCII,JIS,UTF-8,EUC-JP,SJIS". This is a temporary fix for me: [TYPE A] $out_strs = mb_convert_encoding($out_strs, "UTF-8", "ASCII,JIS,UTF-8,EUC- JP,SJIS"); or, [TYPE B] mb_language("Japanese"); $out_strs = mb_convert_encoding($out_strs, "UTF-8", "auto"); Test script: --------------- I'm Englishman, so I'm added this in php.ini; mbstring.language = English mbstring.internal_encoding = UTF-8 And the source code is; $out_strs = mb_convert_encoding($out_strs, "UTF-8", "auto"); Expected result: ---------------- auto SHOULD expand to ASCII,JIS,UTF-8,EUC-JP,SJIS. Why should I change mbstring.language = English to Japs? ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65110&edit=1
