Print unicode characters encoded

Question

Let's say we have string like P\ř\íprava
How can we print it out with Java (println, printf, ...) so the unicode characters won't be decoded?

Final

I ended up using something like this

String data = "P\u0159\u00edprava";
data = data.replace("\\","\\\\");
// "\\" is a single backslash "\\\\" then double backslashes
System.out.println(data);

Answer 1

在您自己的'\\'字符前添加'\\'应该可以解决问题：

System.out.println("P\\u0159\\u00edprava");

Answer 2

转义反斜杠：

System.out.println("P\\u0159\\u00edprava");

Answer 3

Use StringEscapeUtils of commons-lang3 .

The code is here (see the method public boolean translate(int codepoint, Writer out) throws IOException ): http://svn.apache.org/viewvc/commons/proper/lang/trunk/src/main/java/org/apache/commons/lang3/text/translate/UnicodeEscaper.java?revision=1148520&view=markup
