Try this, you'll see it's really easy: <?php //in Unicode mode all strings created this way are Unicode strings $s = "<any unicode string>"; var_dump(strlen(($s))); var_dump(strlen((binary)$s)); ?>

http://www.php.net/language.types.type-juggling#language.types.typecasting No (binary). PHP 4.1.2 = parse error in test2.php on line 5. PHP 5.2.0 = Parse error: syntax error, unexpected T_VARIABLE in test2.php on line 5 It is E_PARSE error, so I can't apply fix after detecting PHP6.

Yes. We're talking of PHP6 here.

Fix is not portable. We are talking about SquirrelMail code. Minimal PHP 4.1.x requirement. Good fix is closer to <?php //in Unicode mode all strings created this way are Unicode strings $s = "<any unicode string>"; var_dump(strlen($s)); // add php6 test here { settype($s,'binary'); // } var_dump(strlen($s)); ?>

In real life this hack would not be required, since you should/would be using streams returning binary data. My example was just to show how to cast unicode to binary string.

I will have to write wrappers for all affected functions. Not wise. strlen("\xC4\x85") = 2. strlen((binary)"\xC4\x85") = 4. Not good. It is one character in utf-8.

I'm afraid I don't understand you again..

Nevermind. Will watch how PHP6-dev changes and wait for better documentation.

Watch? Just watching is pointless. Contribute to the discussions, exchange ideas, help developers - that'll make your life easier eventually. -- Wbr, Antony Dovgal
