Dynamic Ajax Content charset problem

Dynamic Ajax Content
http://www.dynamicdrive.com/dynamici...jaxcontent.htm

When my external page includes characters like "ü,ö,ı", it seems like "?" (My external page has a meta tag "charset=windows-1254" in head section).

When i search forum i see that

I'm sure it should, but I'm afraid that's just not possible. A <meta> tag, not the best of ideas anyway, needs to go in the head; this AJAX script won't necessarily be able to write to the head.

is there nothing to avoid this character problem?

Are you using named or number entities or the actual characters?

The meta tags and anything else in the head section of the external page are lost with this script. You can load javascripts and/or css to the 'top' page for use with the external content using loadobjs(). If you need a meta tag for content on the external page, you could simply put it in the head on the 'top' page.

Thank you for your reply.

My top page has a meta tag like "charset=windows-1254" and also external page has same meta tag.

I am using actual characters.I want to show rss feeds with this dynamic content.

if it will avoid the problem i can replace characters with their named or number entities.(Edit:But i could not found the number entities of the characters like"ı,ğ,ş")

Any good ASCII to hex converter:

http://centricle.com/tools/ascii-hex/

will give you the hex value for a character, the above one precedes it with a % sign. Once you have the number, you can make a number entity for it. In the case of ğ it has a hex value of 11f, so your entity would be - ğ

This may or may not solve your problem though, worth a shot.

This didn't solve the problem.

I have same problem with another Ajax script. Can we add a code to AJAX to write head part of external page?Please help.

If you'r using an external .php, use
header('content-type: text/html; charset=YOURCHARSET');
in the php-file.

I did a simple test here and it worked:

I have the exact same problem. Cannot display greek characters in the external php file. In each page i have charset=utf-8 and all characters are being displayed right until i use the above script. In firefox and opera everything seems right, but in ie i see ?????????? in place of the greek word. I have this problem using either named or number entities of the characters. Adding header('content-type: text/html; charset=utf-8); to the php file didn't help. Any other ideas?

**jscheuer1** · 02-18-2007, 05:07 PM

If using named entities isn't taking care of it, see:

http://www.dynamicdrive.com/forums/s...8&postcount=14

and the thread linked to it.

**apostolidis** · 02-18-2007, 05:46 PM

I added AddDefaultCharset utf-8 to .htaccess file. I tested it locally (with wamp installed) and on my server. It still won't work in ie. Is there a way to modify the script to get this done? If not, any other ideas (or scripts)?
