I can't get rid of wierd characters in my RSS feed

chromis

Hi,

I've created a utf8 encoded RSS feed which presents news data drawn from a database. I've set all aspects of my database to utf8 and also saved the text which i have put into the database as utf8 by pasting it into notepad and saving as utf8. So everything should be encoded in utf8 when the RSS feed is presented to the browser, however I am still getting the wierd question mark characters for pound signs :(

Here is my RSS feed code (coldfusion):

Has anyone any suggestions? I've done loads of research but can't find the right answers :(

Thanks in advance,

does it help if you use £? (I know that may be only a workaraound, but from the code I can tell nothing without the actual feed)

is £ the only character outside the ascii charset? maybe your generator has some problems with utf-8 or doesn't know which charset to use....

PS please don't post your questions in the insights section, ask a moderator to move it to the answers section.

Hi Dormilich thanks for your reply. My apologies, I am aware of the answers section but I accidentally put it in here, it's very easy to make the mistake sadly (preffered the old layout!).

Yes the only bad character is the pound sign, I've tryed replacing it manually in the database presuming that that would replace the chracter with the utf8 equivalent but it didn't work. If i use the £ it breaks the feed. I could use cdata but I need to display paragraph formatting, and using cdata displays the p element tags.

Dormilich

£ breaks your feed because it's an undefined entity (you'd need a DTD to fix that). have you tried £? this should not break the feed.

Ok i've replaced all occurences of £ with £ it now works great thanks! Why would the pound sign not be recognised though, do you think that when i saved the file as utf8 it didn't convert the character properly?
Ideally i would like to create a function in coldfusion which will doctor text and make it utf8 compliant, do you know of the best way to do this?

I am most of the way there with the following function, apart from putting some code in to replace the pound signs what other ways could i improve it?

this is a question more suited in the coldfusion forum. I have never used CF and I'm probably no help there....
