1- The pushState() method if you want to add a new modified URL to history entries.

window.history.pushState("object or string", "Title", "/"+window.location.href.substring(window.location.href.lastIndexOf('/') + 1).split("?")[0]);

This page URL will change from:

파이썬에서 유니코드 스트림 다루기

# 입력 스트림과 출력 스트림을 연다

input = open("input.txt", "rt", encoding="utf-16")  

output = open("output.txt", "wt", encoding="utf-8")

# 유니코드 데이터 조각들을 스트리밍한다

with input, output:

        # 데이터 조각을 읽고

        chunk = input.read(4096)

        if not chunk:
