As the Internet becomes more and more popular, website development and construction are becoming more and more important. In this process, HTML and JSP are the two most commonly used web development languages. However, during development using these two languages, you may encounter garbled code problems. In this article, we will explore the causes and solutions of garbled HTML and JSP.
1. Causes and solutions to HTML garbled characters
The character set of HTML language is based on ISO-8859-1. This character set only recognizes characters for Western European languages. However, with the development of the Internet, more and more countries have begun to use the Internet, and the languages used in these countries are not just Western European languages, which has led to the problem of garbled characters. In addition, using special characters in HTML documents may also cause garbled characters.
Add the tag at the head of the HTML file and specify the character set as UTF-8, that is:
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
This enables characters in various languages to be displayed correctly.
2. Reasons and solutions for JSP garbled characters
Similar to HTML, JSP will also have garbled characters. Garbled characters in JSP are usually caused by the default encoding of the Tomcat server being ISO-8859-1 instead of UTF-8. In addition, using special characters in JSP pages may also cause garbled characters.
Add instructions at the head of the JSP file to specify the character set of the page to be UTF-8, that is:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
Also , you can set the default encoding of the Tomcat server to UTF-8, that is:
-Dfile.encoding=UTF-8
so that characters in various languages can be displayed correctly.
Summary
In the process of using HTML and JSP for web development, garbled code problems are very common. In order to solve this problem, we should correctly specify the character set in the web page. In HTML, you can specify the character set by adding the tag; in JSP, you can specify the character set by adding instructions or changing Tomcat's default encoding. Through these methods, we can correctly display characters in various languages and ensure the normal operation of web pages.
