Error when parsing ISO-8859-1 encoded documents

[Inma Marín López]

Hello all!    I have an xml document which includes special characters, for example,   <Document>             <one>melón</one>             <two>1º</two> </Document>   And I want to get it in canonical form, so I do the following (using Apache XML Security and Xerces 2.7.1):               org.apache.xml.security.c14n.Canonicalizer c14n = org.apache.xml.security.c14n.Canonicalizer.getInstance( org.apache.xml.security.transforms.Transforms.TRANSFORM_C14N_EXCL_WITH_COMMENTS);             byte [] canonicalized = c14n.canonicalize(xmldocument.getBytes());   However, I obtain the following exception:   org.xml.sax.SAXParseException: Invalid byte 2 of 4-byte UTF-8 sequence.             at org.apache.xerces.parsers.DOMParser.parse(Unknown Source)             at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source)             at org.apache.xml.security.c14n.Canonicalizer.canonicalize(Unknown Source)     The xml document is ISO-8859-1 encoded, because I want to keep special characters (if I encode it in UTF-8, the document turns into the following:   <Document>             <one>mel?n</one>             <two>1?</two> </Document>  ).   Could you be so kind as to tell me how to parse an ISO-8859-1 encoded document with xerces, please???? Thank you very much in advance.   Inma.
