It is not a bug of mbstring. 0xb7,0xf6,0xba,0x7e is a correct byte seqence of EUC-JP. Previous Comments: ------------------------------------------------------------------------ [2003-06-28 09:40:13] [EMAIL PROTECTED] URL decoded byte sequance of 'search_words=%B7%F6%BA%7E' is B7E6+BA7E, which is correct EUC-JP character sequence. <?php // sample code $str_euc = sprintf("%c%c%c%c",0xb7,0xf6,0xba,0x7e); echo mb_detect_encoding($str_euc); // output is 'EUC-JP' ?> Encoding detection is not perfect, it may make mistake if the length of string is too short. But, I believe encoding detection of mbstring works fine in this case. B7E6+BA7E is not correct byte sequence of SJIS, UTF-8, ISO2022-JP. It is correct EUC-JP byte sequence. ------------------------------------------------------------------------ [2003-06-24 02:52:51] jc at mega-bucks dot co dot jp Description: ------------ I've just run into a strange "bug". I have a form on my web site that takes input from the user and then uses that to do a search of a postgresql database. The form is set to be EUC-JP, but this weekend a user submitted a query that postgres reject because it "contains invalid EUC-JP" characters. Luckily the error was logged and I was able to track it down. I thought that maybe the user had entered some bad characters in the form or used some strange encoding so I should better check to make sure that the encoding of the submitted form data really is EUC-JP using mb_detect_encoding(). But unfortunately mb_detect_encoding() says that the invalid string *is* in EUC-JP!? The query string is as it appears in the URL is: search_words=%B7%F6%BA%7E In the script that parses this query I have put the following: $words = $_GET["words"]; $enc = mb_detect_encoding($aI["words"]); echo "encoding is $enc and the query is ($words)";die; The result is: encoding is EUC-JP and the query is (喧?) As you can see the query string is *not* a valid EUC-JP sequence ... Reproduce code: --------------- $words = $_GET["words"]; $enc = mb_detect_encoding($aI["words"]); echo "encoding is $enc and the query is ($words)";die; Expected result: ---------------- SJIS (?) or Undefined. mb_detect_encoding() does not specify what it returns if an invalid character sequence for which the encoding cannot be detectec is passed in. In the above case the character sequence is valid SJIS I believe ... Actual result: -------------- EUC-JP ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24309&edit=1
