Android write PDF file whith itextpdf pt-BR language

I need write PDF File, and I use this sample(http://www.vogella.com/tutorials/JavaPDF/article.html) with this version "itextpdf-5.4.1.jar".
This create the PDF file, but when the word has "você" write this "você".
I find this code but has not work:
Document document;
...
...
document.addLanguage("pt-BR");
How set encoding or language to Brasil?
Thanks!

Take a look at my answer to Divide page in 2 parts so we can fill each with different source (this is year another question answered in The Best iText Questions on StackOverflow). In this example, we read a series of text files that are stored in UTF-8. To achieve this, we use this method:
public Phrase createPhrase(String path) throws IOException {
Phrase p = new Phrase();
BufferedReader in = new BufferedReader(
new InputStreamReader(new FileInputStream(path), "UTF8"));
String str;
while ((str = in.readLine()) != null) {
p.add(str);
}
in.close();
return p;
}
If you remove the "UTF8" and if you read that text as if it were ASCII, then you'd get the same behavior you are describing in your question: each byte would be treated as a single character whereas you have characters that require two bytes.
This is not really an iText question. This is a pure encoding question.

How do I go about setting TextView to display UTF-8 when the String is not an embedded Resource?

I'm encountering an odd situation whereby strings that I load from my resource XML file that have Spanish characters in them display correctly in my TextViews, but strings that I'm fetching from a JSON file that I load via HTTP at runtime display the missing char [] boxes
ESPAÑOL for example, when embedded in my XML strings works fine, but when pulled from my JSON is rendered as SPAÃ[]OL, so the Ñ is transformed into a à and a missing char!
I'm not sure at what point I need to intercept these strings and set the correct encoding on them. The JSON text file itself is generated on the server via Node, so, I'm not entirely sure if that's the point at which I should be encoding it, or if I should be encoding the fileReader on the Android side, or perhaps setting the TextView itself to be of some special encoding type (I'm unaware that this is an option, just sort of throwing my hands in the air, really).
[EDIT]
As per ianhanniballake's suggestion I am logging and seeing that the screwy characters are actually showing up in the log as well. However, when I look at the JSON file with a text viewer on the Android file system (it's sitting on the SDCARD) it appears correct.

So, it turned out that the text file was, indeed, encoded correctly and the issue was that I wasn't setting UTF-8 as my encoding on the FileInputStream...
The solution is to read the file thusly:
static String readInput() {
StringBuffer buffer = new StringBuffer();
try {
FileInputStream fis = new FileInputStream("myfile.json");
InputStreamReader isr = new InputStreamReader(fis, "UTF8");
Reader in = new BufferedReader(isr);
int ch;
while ((ch = in.read()) > -1) {
buffer.append((char) ch);
}
in.close();
return buffer.toString();
} catch (IOException e) {
e.printStackTrace();
return null;
}
}

Some hungarian characters are not display properly in android

My XML response is
<name> DPD futár </name>
My XML parsing code
SAXParserFactory _saxFactory = SAXParserFactory.newInstance();
SAXParser _saxParser = _saxFactory.newSAXParser();
XMLReader _xmlReader = _saxParser.getXMLReader();
_shippingMethodList = new ArrayList<ShippingMethodItem>();
ShippingMethodParser _cartLoginParser = new ShippingMethodParser(
_shippingMethodList);
_xmlReader.setContentHandler(_cartLoginParser);
InputSource is = new InputSource();
is.setEncoding("ISO-8859-1");
is.setCharacterStream(new StringReader(response));
_xmlReader.parse(is);
But I got following as string in my name variable.
DPD futár
I also try with
is.setEncoding("UTF-8");
But not getting success. Can anybody please help me regarding this ?

Try this one
InputSource in = new InputSource(new InputStreamReader(url.openStream(),"ISO-8859-1"));

You should not use ISO-8859-1 (latin 1) encoding for Hungarian data since it does not contain national characters like ő. The letter á is also a part of Portugese and Spanish alphabets for example and both are supported by latin 1, but in the case of Hungarian only latin 2 (ISO-8859-2) will work. However you should always use unicode encoding whenever possible.
For first I'd check if the received data is properly encoded since the error may also happen when you encode your string into unicode. The example you provide is a typical encoding error. Maybe you're trying to encode UTF-8 into UTF-8 which is wrong.

how to decode characters in utf - 8 format in android

i have the following text in my strings.xml file
\n\nSVG Service Verlags GmbH & Co. KG \n
Schwertfegerstra?e 1-3\n
D-23556 L?beck\n
this is german text.
i need to decode this using utf-8 and then set it as text of a textview.
how do i go about this
thank you in advance.
EDIT:
i have tried the following
String decodedstring = URLDecoder.decode(nodevalue, "UTF-8");
this also does not work. why does this not work?

Some things to check.
Make sure your xml is tagged with the right encoding.
Make sure your xml file is SAVED with the right encoding. Looking at the text you pasted (from a browser?) it looks like the file is already mangled. Schwertfegerstra?e should be Schwertfegerstraße.
When you open the file you need to use an InputStreamReader with the encoding set.
See this page for an example:
http://www.mkyong.com/java/how-to-read-utf-8-encoded-data-from-a-file-java/
The key bit is:
BufferedReader in = new BufferedReader(
new InputStreamReader(
new FileInputStream(fileDir), "UTF8"));

reading unicode text from assets

Trying to read an utf-8 encoded file in android...
InputStreamReader reader = new InputStreamReader(assets.open("data.txt"), "UTF-8");
BufferedReader br = new BufferedReader(reader);
String line;
//The line below throws an IOException!!
line = br.readLine();
What's wrong with this code?

It looks like you file is too big, you have to split it onto several files (1048576 bytes maximum for each) or find another way to reduce file size. Here is an article about similar problem http://androidgps.blogspot.com/2008/10/dealing-with-large-resources.html
