将txt文件从ANSI转换为UTF-8，以编程方式 [英] Converting a txt File from ANSI to UTF-8 programmatically

问题描述

我需要你的帮助。
我正在研究将数据从txt文件转换成数据库的java应用程序，问题是文件有ANSI编码，我不能改变，因为它来自我的应用程序外面，当我写数据库中的数据我有一些???内。
我的问题是，如何将我从文件中读取的数据从ANSI转换为可以处理这些被排除的符号的UTF-8。
我已经尝试过Byte []到String转换，但没有起作用。

解决方案

解读Reader 如下所示：

  Reader reader = 
 new InputStreamReader（inputStream，Charset.forName （encodingName））; 
  

您应该使用哪个编码名称的Exaclty取决于其中编写了文本文件的ANSI编码。您可以找到Java 6支持的编码列表here 。如果它是一个英文系统，它可能是 windows-1252 。

将数据写入数据库正确地依赖于正确配置数据库（有时）为JDBC驱动程序提供正确的配置。

您可以在这里和这里。

I need your help here please. I'm working on a java application that convert data from a txt file into the database , The problem is that the file have ANSI encoding which i can't change because it comes from outside my application ,and when i write the data to the database i got some "???" inside. My question is , how can i convert the data that i read from the file from ANSI to UTF-8 which can handle those weired symbols. I've tried the Byte[] to String converting but it didn't work.

解决方案

Use open a decoding Reader like this one:

Reader reader = 
   new InputStreamReader(inputStream, Charset.forName(encodingName));

Exaclty which encoding name you should use depends on which "ANSI" encoding the text file was written in. You can find a list of encoding supported by Java 6 here. If it is an English-language system, it will likely be windows-1252.

Writing data to the database correctly depends on configuring the database correctly and (sometimes) providing the right configuration to the JDBC driver.
