Em sử dụng regex này xem sao: [0-9a-zA-Z]+

Ví dụ: 

System.out.println("Dung".matches("[0-9a-zA-Z]+")); // true
System.out.println("Dũng".matches("[0-9a-zA-Z]+")); // false

System.out.println("Dung".matches("[0-9a-zA-Z]+"));// true trường hợp này chr check được 1 từ anh à từ 2 từ sẽ false System.out.println("Dung nam".matches("[0-9a-zA-Z]+")); // false  –  Thân Nam 1661472834000
Vậy em dùng pattern này em ạ: System.out.println("Dung Name".matches("[0-9a-zA-Z\\s]+")); // true  –  tvd12 1661503874000
