我正在尝试在ANT脚本中支持UTF-8字符。
只要字符串由2字节UTF-8字符组成，例如：
然后事情很好。
当我使用Unicode Han Character时：
根据这个网站： http://www.fileformat.info/info/unicode/char/6211/index.htm 具有0xE6 0x88 0x91
的UTF-8编码我可以在UltraEdit中看到，我的输入属性文件连续都有值“E6 88 91”，所以我相信我的输入是正确的。当我在Notepad ++中打开相同的文件时，我可以正确地看到所有字符。
这是我的构建脚本：
<?xml version="1.0" encoding="UTF-8" ?>
<project
name="utf8test"
default="all"
basedir=".">
<target name="all">
<loadproperties encoding="UTF-8" srcfile="./apps.properties.all.txt" />
<echo>No encoding ${common.app.name}</echo>
<echo encoding="UTF-8">UTF-8 ${common.app.name}</echo>
<echo encoding="UnicodeLittle">UnicodeLittle ${common.app.name}</echo>
<echo encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked ${common.app.name}</echo>
<echo>${common.app.ServerName}</echo>
<echo>${bb.vendor}</echo>
<echo>No encoding ${common.app.UserIdText}</echo>
<echo encoding="UTF-8">UTF-8 ${common.app.UserIdText}</echo>
<echo encoding="UnicodeLittle">UnicodeLittle ${common.app.UserIdText}</echo>
<echo encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked ${common.app.UserIdText}</echo>
<echoproperties />
</target>
</project>
这是我的属性文件：

感谢您的帮助
编辑\更新6/19/2012
我正在Windows环境中开发。
我从以下位置安装了TTF： http://freedesktop.org/wiki/Software/CJKUnifonts/Download
我更新了UltraEdit以使用TTF，我可以看到中文字符。
<?xml version="1.0" encoding="UTF-8" ?>
<project name="utf8test" default="all" basedir=".">
<target name="all">
<echo>我們</echo>
<echo encoding="ISO-8859-1">ISO-8859-1 我們</echo>
<echo encoding="UTF-8">UTF-8 我們</echo>
<echo file="echo_output.txt" append="true" >我們 ${line.separator}</echo>
<echo file="echo_output.txt" append="true" encoding="ISO-8859-1">ISO-8859-1 我們 ${line.separator}</echo>
<echo file="echo_output.txt" append="true" encoding="UTF-8">UTF-8 我們 ${line.separator}</echo>
<echo file="echo_output.txt" append="true" encoding="UnicodeLittle">UnicodeLittle 我們 ${line.separator}</echo>
<echo file="echo_output.txt" append="true" encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked 我們 ${line.separator}</echo>
</target>
</project>
在UltraEdit中运行捕获的输出是： 构建文件：E：\ temp \ utf8 \ build.xml
all:
[echo] ??
[echo] ISO-8859-1 ??
[echo] UTF-8 ??
BUILD SUCCESSFUL

echo_output.txt文件显示如下：
??
ISO-8859-1 ??
UTF-8 ??
ÿþU n i c o d e L i t t l e ? ?
U n i c o d e L i t t l e U n m a r k e d ? ?
因此，我的ANT环境设置方式似乎存在一些根本性的错误，因为我不能简单地将字符回显到屏幕或文件中。
答案 0 :(得分：0)
java.util.Properites类使用ISO 8859-1编码。使用Ant 1.8.2进行测试时，以下工作正常。
<强>的build.xml
<?xml version="1.0" encoding="UTF-8" ?>
<project name="utf8test" default="all" basedir=".">
<target name="all">
<loadproperties encoding="ISO-8859-1" srcfile="./apps.properties.all.txt" />
<echo>No encoding ${common.app.name}</echo>
<echo encoding="ISO-8859-1">ISO-8859-1 ${common.app.name}</echo>
</target>
</project>

答案 1 :(得分：0)
我通过首先通过此编码器传递所有输入（属性文件）来解决我在Windows和MacOS上的问题。然后，当输入以这种方式转义时，ANT可以正确读取，然后写入值。
StringBuffer buffer = new StringBuffer();
try
{
FileInputStream fis = new FileInputStream(input);
InputStreamReader isr = new InputStreamReader(fis, "UTF8");
Reader in = new BufferedReader(isr);
int ch;
while ((ch = in.read()) > -1)
{
if (ch > 127 || ch < 0)
{
String hex = Integer.toHexString(ch);
switch (hex.length())
{
case 1:
buffer.append("\\u000");
break;
case 2:
buffer.append("\\u00");
break;
case 3:
buffer.append("\\u0");
break;
case 4:
default:
buffer.append("\\u");
break;
}
buffer.append(hex);
}
else if (ch != 0)
{
buffer.append((char) ch);
}
}//while
in.close();
//System.out.println(buffer.toString());
}//try
catch (IOException e)
{
//e.printStackTrace();
throw new BuildException(e.getMessage() );
}
try
{
FileOutputStream fos = new FileOutputStream(dest);
Writer out = new OutputStreamWriter(fos, "windows-1252");
out.write(buffer.toString());
out.close();
}
catch (IOException e)
{
throw new BuildException(e.getMessage() );
}
