# Unicode Block

* Determine which type of language that the string contains

```java
String str = "大家,!｡驚いた彼は道を走っていった";
char [] charList = str.toCharArray();
for (char c : charList) {
	Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
	System.out.println(ub);
}
```

* English mostly is Basic\_Latin
* Chinese mostly is CJK\_UNIFIED\_IDEOGRAPHS
