Question : How to solve a save problem in eclipse?

In the Message.java contains japanese character.  So, when I save the file the error below display.

Save problems:

Some characters cannot be mapped using "Cp1252"
character encoding. Either change the encoding
or remove the characters which are not supported
by the "Cp1252" character encoding.

or use unicode encoding to specify the string.
