What is StringUtils.stripAccents in Java?

stripAccents() is a static method of the StringUtils class that is used to remove diacritics from the input string.

The stripAccents() method replaces the accented characters with their unaccented equivalent without altering the case of the character. For example, the character Č is replaced by C.

The method returns null if the input string points to a null reference.
