Try using BufferedReader and its readLine() method.
In my impression gotten from past experiences, DataInputStream
and its readUTF() method are semi-deprecated APIs.
They are not simpile nor easy to use and can often bring troubles.
Read the API documentation for DataInput#readUTF() method.
Be amazed at its complicatedness and awkwardness of the
description.

Someone just made this same mistake in a another post.

readUTF is NOT for reading UTF-16 or UTF-8 text files. It is for
reading binary format files containing counted strings with binary
lead counts.

you want a FileReader using  explicit UTF-8 encoding.

see http://mindprod.com/applets/fileio.html
for the sample code.

Despite its name, DataInputStream.readUTF() does NOT read UTF-8 or any other
Unicode format.

If you want to read Unicode text, use a Reader with an appropriate character
encoding.

with this code I can read UC-16 text files BUT with big endian char
storing (I created a php script for precompile convertion from little to
big endian)
------------------------------
static public String loadFile(String s) throws Exception {
    DataInputStream isr = new
DataInputStream(LanguageLoader.class.getResourceAsStream(s));
    s = "";
    int z = isr.available() / 2;
    for(; z > 0; z--)
        s += isr.readChar();
    return s;
}
------------------------------
the problem is that I run readChar() inside a loop and I don't trust
speed of such operations in Java (specially java for mobiles)
