@PropertySource and UTF-8 properties file

Question

Is it possible, using @PropertySource annotation, to configure the encoding that has to be used to load the property file?

An example to clarify my problem

@Configuration
@PropertySource("classpath:/myprop.properties")
public class MyApplicationContext {

    @Autowired(required = true)
    private Environment env;

    @Bean
    public MyBean myBean() {
       return new MyBean(env.getRequiredProperty("application.name"));
    }

}

myprop.properties is aUTF-8 file but, no matter what, "application.name" is interpreted as ISO-8859-1.

The workaround is to escape special chars in the properties file, but setting the encoding was possible with the old context:property-placeholder so I think it should be possible to do the same with @PropertySource

Answer 1

It is now possible:

@PropertySource(value = "classpath:/myprop.properties", encoding="UTF-8")

Answer 2

.properties files are per definition ISO-8859-1 encoded. So I'm afraid you can't do that.

You can however use \uXXXX unicode escapes to represent any unicode character you want. The (slightly misnamed) native2ascii tool can help with automatically doing that.
