ID: 31805 Updated by: [EMAIL PROTECTED] Reported By: gullevek at gullevek dot org Status: Feedback Bug Type: mbstring related Operating System: gnu/linux PHP Version: 4.3.10 New Comment:
You look somewhat confused. First off, ISO-2022-JP is a "stateful" multibyte encoding and quite different from other stateless multibyte encodings such as Shift_JIS , EUC-JP and UTF-8. What makes it "stateful" are escape sequences used to determine in which way consecutive octets following such an escape sequence are interpreted by the implementation. With ISO-2022-JP, a single hiragana character most likely ends up with 8 bytes in a stream due to prepended "Shift-in" and appended "Shift-out" which are needed to switch the interpretation mode, to "JIS-kanji" and to "ASCII" respectively, while two hiragana characters would result in 10 bytes because those escape sequences are only needed when entering a chunk of multibyte "JIS-kanji" characters and leaving the chunk. If the problem you are experiencing are actually caused by the wrong encoding detection, then setting mbstring.language to "Japanese" may fix it. Encoding detection is based on a kind of heuristics, so its behaviour may vary between the releases.

But I don't know why 4.3.10 behaves different to 4.3.9 ... <?php import_request_variables("p"); if ($send) { echo "S: $string<br>"; echo "D: ".mb_detect_encoding($string,"iso-2022-jp")."<br>"; echo strlen($string)." -- without iso: ".mb_strlen($string)." -- with iso".mb_strlen($string,"iso-2022-jp")."<br>"; } ?> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-2022-JP"> </head> <body> <form method="post" name="foo" enctype="multipart/form-data"> <input type="text" name="string" size="50" value="<? echo $string; ?>"><br> <input type="submit" name="send" value="Send"> </form></body></html> ------------------------------------------------------------------------ [2005-02-02 08:41:18] [EMAIL PROTECTED] Please post the script somewhere online and provide a link (otherwise your Kanji might screw up in our form). ------------------------------------------------------------------------ [2005-02-02 08:40:52] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
