Hi Inma,
The last line of your first block you have:
return
baos.toString();
Note that when you do “toString()” on the byte array it will
return a string in Java internal form, not UTF8. I’m guessing that in your
next block of code, xmlutf8 is the result of the first block. This means that
when you getBytes() from it, you are getting bytes that are no longer in UTF8
form.
HTH,

Subject: Problems with ISO-8859-1 and UTF-8 encodings
Hi
all,
I
have some problems with ISO-5589-1 and UTF-8 encodings in XML documents.
Concretely, I have this ISO-8859-1 - encoded XML document:
<?xml
version="1.0" encoding="ISO-8859-1"?>
<DOCUMENTO>
<PERFILES>Á</PERFILES>
<PERFILES>É</PERFILES>
<PERFILES>Í</PERFILES>
<PERFILES>Ó</PERFILES>
<PERFILES>Ú</PERFILES>
</DOCUMENTO>
Then
I UTF-8 - encode it, by means of the following piece of code:
Transformer transformer = TransformerFactory.newInstance().newTransformer();
StreamSource ds = new StreamSource(new
ByteArrayInputStream(xmliso88191.getBytes()));
transformer.setOutputProperty(OutputKeys.ENCODING,"utf-8");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
transformer.transform(ds,new StreamResult(baos));
return baos.toString();
to
obtain this XML document:
<?xml
version="1.0" encoding="utf-8"?>
<DOCUMENTO>
<PERFILES>Ã?</PERFILES>
<PERFILES>É</PERFILES>
<PERFILES>Ã?</PERFILES>
<PERFILES>Ó</PERFILES>
<PERFILES>Ú</PERFILES>
</DOCUMENTO>
Next,
I ISO-8859-1- encode this document (UTF-8 encoded):
Transformer transformer = TransformerFactory.newInstance().newTransformer();
StreamSource ds = new StreamSource(new
ByteArrayInputStream(xmlutf8.getBytes()));
transformer.setOutputProperty(OutputKeys.ENCODING,"iso-8859-1");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
transformer.transform(ds,new StreamResult(baos));
return baos.toString();
But
I can not get it. Instead, I obtain the following exception:
[Fatal
Error] :8:11: Invalid byte 2 of 2-byte UTF-8 sequence.
javax.xml.transform.TransformerException:
org.xml.sax.SAXParseException: Invali

at org.apache.xalan.transformer.TransformerIdentityImpl.transform(Trans
ormerIdentityImpl.java:432)
Is
this process correct? Supposing that it is, it seems the exception is due to
‘Ã?’ characters (‘Á’ and ‘Í’ UTF-8 – encoding), so I would like to know
how I could UTF-8 - encode ‘Á’ and ‘Í’ characters and then, back them to
ISO-8859-1 encoding.
Could
anybody be so kind as to help me, please?
Thank
you very much in advance.
Inma.
