multibyte post data automatically encoded?
Hi,
When I post some multibyte chars to a test script, the html output is presented as numeric unicode entities, like ڸ etc, even though I didn't use any encoding functions on it. For instance: some arabic chars came out as ﺙﺀﺐ I looked at the mbstring settings in phpinfo but it's all set to: off, NULL, pass, neutral Could somebody explain this to me? Here's the test script I used: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/> </head> <body> <?php echo $_POST['val']; ?> <form method="post"> <textarea name="val"></textarea><br> <input type="submit" value="submit"> </form> </body> </html> Thanks, Jos

It's the client that's doing it, it's not a setting in PHP. If you want to avoid this, you likely need to send the page encoded in utf-8, so the browser can send utf-8 back again, which covers pretty much everything. You can then work out how you want to handle characters outside of your target encoding yourself. -- Andy Hassall :: andy@andyh.co.uk :: http://www.andyh.co.uk http://www.andyhsoftware.co.uk/space :: disk and FTP usage analysis tool

It's the client that's doing it, it's not a setting in PHP. I see. Of course. Another question, if I may: how does the browser tell the difference between multiple bytes and multibytes? Is it inferred from the bit patterns? Thank you, Jos
