Hi, i have a problem with UTF-8. I want to add special characters, like german umlauts: äöü or french characters: e.g. é in my XML-File. I can add the characters to an xml-file, but when i try to read thegenerated file with the SAXParser, an error will occure (Invalid byte 2of 3-byte UTF-8 sequence) - see at the end of this message. The XML-File looks fine in my editor (UltraEdit), but my System.out-Trace show this: äöü for äöü. With ISO-8859-1 everything works fine. Where is my mistake?
I searched the dom4j faq, cookbook and internet for this problem, but the only thing i found was this: http://sourceforge.net/mailarchive/message.php?msg_id=10356047 It didn't help... Thanks for any advice!
