Reading from property file containing utf 8 character

Question

I am reading a property file which consists of a message in the UTF-8 character set.

Problem

The output is not in the appropriate format.

Answer 1

Use props.load(new FileReader("uinsoaptest.properties")) instead. By default it uses the encoding Charset.forName(System.getProperty("file.encoding")) which can be set to UTF-8 with System.setProperty("file.encoding", "UTF-8") or with the commandline parameter -Dfile.encoding=UTF-8.

Answer 2

Use an InputStreamReader with Properties.load(Reader reader):

FileInputStream input = new FileInputStream(new File("uinsoaptest.properties"));
props.load(new InputStreamReader(input, Charset.forName("UTF-8")));

Answer 3

You should specify the UTF-8 encoding when you construct your FileInputStream object. You can use this constructor:

new FileInputStream("uinsoaptest.properties", "UTF-8");

If you want to make a change to your JVM so as to be able to read UTF-8 files by default, you will have to change the JAVA_TOOL_OPTIONS in your JVM options to something like this :

-Dfile.encoding=UTF-8

Answer 4

If somebody use @Value annotation, could try StringUils.

@Value("${title}")
private String pageTitle;

public String getPageTitle() {
    return StringUtils.toEncodedString(pageTitle.getBytes(Charset.forName("ISO-8859-1")), Charset.forName("UTF-8"));
}
