read unicode from file

[gert]

I want to read a unicode String from a file:
FileInputStream stream = new FileInputStream(file);

DataInputStream din = new DataInputStream(stream);
byte[] y = new byte[6];
din.read(y);
String unit = new String(y, "UTF-8");
din.close();

If the file contains the entry \u00B0 I would expect if displaying unit
on a JLabel see the 'degree' sign (°).
But I see this: \u00B0
If I do the following: String unit = "\u00B0" an display this unit on a
JLabel it displays the '°' correctly.
What do I do wrong??
Many thanks for any help

Read the stuff using a Reader do not use a plain InputStream

Reader r = new InputStreamReader(new FileInputStream(file), "UTF-8"));

Read the stuff using a Reader do not use a plain InputStream

Reader r = new InputStreamReader(new FileInputStream(file), "UTF-8"));

Apart from that I understand that the file contains a literal backslash, a "u"
and four digits (as opposed to the file containing the byte sequence that is
represented by "00B0" in hex). Otherwise an InputStream would still not produce
the described output. If this is true, using a Reader will not help.

In that case you can refer to the following article, where it was discussed how
you can parse strings of your type:
