Editor content is cutted when viewing the source code

Hello...

I have a web page that shows a FCKEditor control. The content of the control is read from the database (an ntext field).

The problem is that when I press "Source" button, only part of the content is shown (the first xx characters, not constant).

I thought that there is an strange character that makes FCKEditor to stop reading the content, because the ntext field is inserted through an e-mail sent from a hotmail account.

I tried to find that character but it was impossible. I loaded the content into an array of characters but I din't find anything strange.

Another fact. When I copied and pasted the content into Notepad, and then copied and pasted back to the FCKEditor, "Source" button shows all the content correctly.

I need an advice to solve this.. I am using FCKEditor in an ASP.NET application.

Thanks a lot in advance,
Jaime
