How to remove control characters from java string?

August 7, 2023 by Tarik

You can do something like this if you want to delete all characters in other or control uni-code category

System.out.println(
    "a\u0000b\u0007c\u008fd".replaceAll("\\p{Cc}", "")
); // abcd

Note : This actually removes (among others) ‘\u008f’ Unicode character from the string, not the escaped form “%8F” string.
