RSS Problem

werushka · February 3, 2008

In my web site i have rss.php it is working fine but the special characters does not show right some characters I can not see and some characters I see as ?.

I checkt the DB and it seems that everything is fine there...

What am I doing wrong?

Really appreciate any feed back.

This is because those characters were copied from Microsoft Word or some other program with unique special characters. Simply retype those characters in (or use the html substitute) and that should fix your problem.

Thanks for you reply.

Actually in rss.php there are no special characters. In my web site there are special characters like headline have special characters and sows allright on the web site. But unfortunitally if the use wants to click on RSS icon to keep an eye of the headlines s/he can do it but in tht case the special characters are noe shown correctly.

Hope I a clearer.

Try coping all of the text in the rss feed into textpad or something then copying it back. You need to make sure that all of the special formatting is removed.

Ok this is what I done I have removed all the special charaters from rss.php and than I have copied all selected text into texpad than pasted it than copied again and pasted in the rss.php on the server from plesk file management utility.

But it does not work...there is a trick on doing it but I don't know how.
