Correct Message

Your task is to remove all non-alphabetic characters from a given string. The input string may include digits, punctuation marks, spaces, and various special characters. You need to output a new string which consists solely of the alphabetic characters (i.e. letters 'a' to 'z' and 'A' to 'Z') in the order they appear in the input.

For example, given the input H3ll0 W0rld!, the output should be HllWrld after removing all non-alphabetic characters.

This problem tests your understanding of string manipulation and filtering techniques. The solution may be implemented in any language that supports standard input and output.
