Is it easy to cut pictograms out of natural text? It’s easy!

Code

// <!-- https://mvnrepository.com/artifact/org.nlp4j/nlp4j-core -->
// import nlp4j.Document;
// import nlp4j.impl.DefaultDocument;
// import nlp4j.util.DocumentUtil;

String text = "😊";
Document doc = new DefaultDocument();
doc.putAttribute("text", text);

EmojiAnnotator ann = new EmojiAnnotator();
ann.setProperty("target", "text");
ann.annotate(doc);

System.err.println(DocumentUtil.toJsonPrettyString(doc));

Result
