打印已编码的unicode字符

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
