Hi everyone

I'm struggling for some days with char encoding problem.

No matter if I save my resource with UTF-8, or ASCII, with

options.put(XMLResource.OPTION_ENCODING, "UTF-8");

the persisted XML mirrors that reality <?xml encoding=...>

however, when I load the resource with the same options, it always give me strings like "a��o�" if they have latin characters.

Anyone can help me?

Thanks in advance

When loading, the encoding in the XML itself is used, i.e.,
XMLResource.OPTION_ENCODING is a save option. Furthermore, the
processing to convert the bytes to characters is done by SAX itself, so
if the right characters are not coming out, then the problem must be
that the right characters are not in the file itself. One way this
could happen is if you edit the file and save it with an encoding
different from what's declared in the XML header.

Hi. Thanks for replying.

Actually, I think my problem is related to another thing.
I'm creating an Eclipse IFile from an InputStream which is created from a string containing the model.
After that I get XMIResource from this file.

Is that possible my problem is related with the fact of being creating an eclipse file first.

Thanks in advance

And how exactly are you doing that? Are you making sure your string ->
byte conversion is using the encoding specified in the String? EMF has
a handy utility
org.eclipse.emf.ecore.resource.URIConverter.ReadableInputStream.getEncoding(String)
for determining the encoding specified by an XML string; you should use
that to convert your string to bytes.
