When I read files with a RandomAccessFile, I get them in Unicode
format. I have been trying, but can't really use that with the rest of
my syntax, like for example searching for character patterns et.c. . How
can I convert it to characters in the English language?

Regards,

In Java characters are unicode.

If you read bytes from your RandomAccessFile then you can convert
them to String using the appropriate String constructor.

<http://java.sun.com/javase/6/docs/api/java/io/InputStreamReader.html>
<http://java.sun.com/javase/6/docs/api/java/io/InputStreamReader.html#InputStreamReader(java.io.InputStream,
java.lang.String)>

Something like

Reader rdr = new InputStreamReader(
new FileInputStream( someFile ),
"UTF-8"
);

You assume that RandomAccessFile is not a requirement ?

By Unicode I assume you mean the raw Unicode bytes.

What about:

RandomAccessFile raf =
new RandomAccessFile( new File( "test" ), "rw" );
byte[] buff = new byte[LEN];

raf.read( buff );
String s = new String( buff, "UTF-8" );

?

There are some "UTF-like" methods in RandomAccessFile, but the docs
admit the methods aren't complete and won't read full Unicode. This
method should be 100% Unicode compatible and easy to change to other
types of encoding too, should you need to in the future.
