SAX Parser doesn't recognize windows-1255 encoding

问题

I'm working on a rss parser in android (upgrading a parser I found on the internet). From what I know SAX Parser recognize the encoding automatically from the xml tag, but when I try to parse a feed that declare windows-1255 encoding it doesn't parsing it and throws and exception. I tried few things:

final InputSource source = new InputSource(feed);
Reader isr = new InputStreamReader(feed);
source.setCharacterStream(isr);

I even tried telling him the specific encoding.
```
source.setEncoding("Windows-1255");
```

Tried to look at the locator:

@Override
public void setDocumentLocator(Locator locator) {
}

And it recognize the encoding as UTF-16.

Please help me solve this annoying problem! Sorry for the mess with code snippets the code button refuse to work for some reason.

Chances are the platform itself doesn't know about the "windows-1255" encoding. After all, it's a Windows-based encoding - I wouldn't want to rely on it being available on any other platforms, particularly mobile ones where things are generally cut down to the "must-have" options.

You need to set the encoding to the InputStreamReader.

Reader isr = new InputStreamReader(feed, "windows-1255");
final InputSource source = new InputSource(isr);

From javadoc the logic for reading from InputSource goes something like this:

Is there a character stream? if there is, use that(This is what happens if you use a Reader like InputStreamReader)

Otherwise:

No character stream? Use byte stream. (InputStream)
Is there a encoding set for InputSource? Use that
There was no encoding set? Try parsing the encoding from the xml file
