Servlet在Mac上用美国国际键盘得到奇怪的字符 [英] Servlet gets weird character with US International keyboard on Mac

问题描述

我有一个简单的表单，我可以输入一些字符。这些字符被发送到执行getBytes并打印字节的servlet。 ã的正确UTF-8字节是-61和-93，但我得到-52和-93。 ：（

I have a simple form where I can type some characters. These characters are sent to a servlet which does a getBytes and print the bytes. The correct UTF-8 bytes for a "ã" are -61 and -93, but I get -52 and -93. :(

我试过一切来理解和解决这个问题，但没有什么工作，我的机器上的一切都应该是UTF-8，所以我怀疑它与美国国际键盘我已经使用了20年。

I tried everything to understand and fix this, but nothing worked. Everything on my machine should be UTF-8 so I suspect it has to do with the US International keyboard I have been using for 20 years.

有聪明的灵魂有从-52和-93来自哪里的线索？

Does any smart soul have a clue from where -52 and -93 are coming from?

推荐答案

这是 Mac OS罗马字符编码。（0xBB == -52。）

That is the Mac OS Roman character encoding. (0xBB == -52.)

有些事要检查：

• getBytes（string，UTF-8） UTF-8）。


• 表单应以UTF-8格式发送： response.setContentType（text / html ; charset =UTF-8）; 。在JSP <％@ page pageEncoding =UTF-8％>


• form action =...accept-charset =UTF-8>

• getBytes(string, "UTF-8") and new String(bytes, "UTF-8").
• The form should have been sent in UTF-8: response.setContentType("text/html; charset="UTF-8");. In a JSP <%@page pageEncoding="UTF-8"%>
• <form action="..." accept-charset="UTF-8">

没有任何帮助：

As all that did not help:

Set the request filtering in your web application (web-xml).

pom.xml中的编码：
