How to display multi-byte characters in Groovy?

Question

This following code showing ?????, when I giving multi byte language Ex : Chinese

import groovy.json.JsonSlurper

def jsonObj = new JsonSlurper().parseText( '{ "name":"怎么样", "age": 23}')

println jsonObj.name

println jsonObj.age

Output :

???????

23

Do I need to do any encoding and decoding to process this ?

If Yes, how I need to pass that value as a Json argument to above ParseText method ?

Answer 1

As per the below API, there is a method where you may pass arguments to specify the Charset.

http://docs.groovy-lang.org/latest/html/gapi/groovy/json/JsonSlurper.html

Below method may be useful. Convert your text to byte array and use below method.

parse(byte[] bytes, String charset)

Another scenario that I can think of is that your source file is encoded using a charset which is not the default charset of your OS.

正如Jon Skeet所说：您需要一个具有Unicode的控制台（例如eclipse的grep控制台： http : //marian.schedenig.name/projects/grep-console/ ）才能正确格式化输出。

Answer 3

It isn't a json issue at all. Json implementation here works with old good java 2 bytes unicode chars. Hieroglyphs aren't a problem for it. The problem is in your output encoding. Is it a Windows or Mac console?

Proof code:

def jsonObj = new JsonSlurper().parseText( '{ "name":"怎么样", "age": 23}')
Writer unicodeFileWriter = new OutputStreamWriter( new FileOutputStream("herogliph.txt"), "UTF-8");
unicodeFileWriter.write(jsonObj.toString());
unicodeFileWriter.close()

The resulting herogliph.txt contains a valid name.

Try something like this.

PrintStream out = new PrintStream(System.out, true, "UTF-8");
out.println(unicodeMessage);
