Reading strings in Unicode

Question

Hi, I have a Java application that reads data from the console and prints it.

If I enter a Unicode string in the Console, for example \ u06F1, it will print \ u06F1 instead of "?".

What change should I make to the code to display the character as "?".

thank

Generally speaking, you should do the following

• use regex to find all occurrences of the following:

  \ and [0-9a-FA-F] {4};

• Then you should use Integer.parseInt()the numeric part;

• Finally, you must replace the string with an integer by char.

Does that make sense to you?
