Count Characters in a String

Given a string, count the frequency of each unique character in the string. Your task is to output each character along with its count on a new line, following the order of their first appearance in the input.

All characters are considered, including letters, digits, symbols, and whitespace. If the input is an empty string, no output should be produced.
