UTF8 java + arabic

[Lucy Sommerman]

Hi - I need to get arabic into a java string. Have saved the arabic as UTF-8, wondering about the correct way to get that into a string? googling gives me lots of suggestions, so just wondering which is the correct one.

Thanks

How is this data currently stored? Binary in a database?

text file - as utf-8

Ok, then you want to be concerned with how you're reading in that data. that is, Use a ByteBuffer with UTF-8 encoding, as following:

try {
        BufferedReader in = new BufferedReader(
            new InputStreamReader(new FileInputStream("infilename"), "UTF8"));
        String str = in.readLine();
    } catch (UnsupportedEncodingException e) {
    } catch (IOException e) {
    }

thanks u r a lifesaver. L

just to check.

and the string itself will be UTF8 though and not converted to UTF 16? this is plugging into something else, will not handle UTF 16 - thanks

Hi:

I am having some difficulty with UTF-8 encoded
chracaters in Java.

My XML has a question which has cyrillic characters. My Java servlet renders this as HTML with a form for the reply.
The HTML produced
displays OK in the browser (the response type on the
Java servelet has to be set to "text/html;
charset=UTF-8" for this to work).

I have to send cyrillic characters back in the
response to the question, in a text field on the form.
The browser is sending back a byte stream (which I am
printing here as hex): d0b3d0bed180d0bed0b4 (this is a
cyrillic word correctly coded as utf-8).

However, on collecting the response (using
request.getParameterValues(fieldname))the servlet
returns the byte stream: d0b3d0bed13fd0bed0b4.
A mistake in the fifth byte!

Has anyone heard of this problem? I suspect the
problem is in the JAVA UTF-8 converter.

Regards

Graham

I now know the answer, thanks to Bruno Van Haetsdaele .

Before calling request.getParameterValues(fieldname));
one should call request.setCharacterEncoding("UTF-8");

Strings are sequences of characters which are 16-bit (UFT-16). You can (and probably need to) convert the String to byte array or write to stream to plug it into "something else". In both cases character encoding can be specified.
