【问题描述】：
字符集编码格式有点新。我有一个 ant 构建脚本，它以 ISO-8859-1 格式编译我的 java 代码。它工作正常。
阅读几篇文章后： How do I convert between ISO-8859-1 and UTF-8 in Java?
我已将字符集格式更改为 UTF-8，从那时起编译问题就开始了。
抛出的错误是：
[javac] TestEncoding.java (at line 11)
[javac] case '?' :
[javac] ^^^^^^^^
我的构建脚本如下：
<javac compiler="org.eclipse.jdt.core.JDTCompilerAdapter"
destdir="bin" debug="true" deprecation="on" encoding="iso-8859-1"
source="1.6" target="1.6"
debuglevel="lines,source" failonerror="false" errorProperty="buildFailed">
<compilerarg line="-warn:+raw" />
<compilerarg line="-warn:-serial" />
<compilerarg line="-log source/testapp/compileLog.xml" />
<src path="testapp" />
<classpath refid="application.classpath" />
</javac>
我的一个有问题的班级中有以下代码：
public class TestEncoding {
public static final String filterAccent(String s) {
StringBuffer sb = new StringBuffer();
int n = s.length();
for (int i = 0; i < n; i++) {
char c = s.charAt(i);
switch (c) {
case 'á':
sb.append("a");
break;
case 'à':
sb.append("a");
break;
case 'ã':
sb.append("a");
break;
case 'À':
sb.append("A");
break;
case 'â':
sb.append("a");
break;
case 'Â':
sb.append("A");
break;
case 'ä':
sb.append("a");
break;
case 'Ä':
sb.append("A");
break;
case 'å':
sb.append("a");
break;
case 'Å':
sb.append("A");
break;
case 'ç':
sb.append("c");
break;
case 'Ç':
sb.append("C");
break;
case 'é':
sb.append("e");
break;
case 'É':
sb.append("E");
break;
case 'è':
sb.append("e");
break;
case 'È':
sb.append("E");
break;
case 'ê':
sb.append("e");
break;
case 'Ê':
sb.append("E");
break;
case 'ë':
sb.append("e");
break;
case 'Ë':
sb.append("E");
break;
case 'í':
sb.append("i");
break;
case 'ì':
sb.append("i");
break;
case 'ï':
sb.append("i");
break;
case 'î':
sb.append("i");
break;
case 'Ï':
sb.append("I");
break;
default:
sb.append(c);
break;
}
}
return sb.toString();
}
}
我也尝试将字符集更改为 UTF-16，但这次却抛出了不同的错误：

有人可以帮忙吗？
感谢和问候，

【问题讨论】：
-
确保
javac任务的encoding属性与源文件的真实编码匹配。 -
我的源文件字符编码是 cp-1252。但是使用 ISO-8859-1 可以正常工作，而 UTF-8 则不行。
-
CP-1252 和 ISO-8859-1 是非常接近的编码，大多数字符的表示方式相同。尝试以 UTF-8 对源文件进行编码，并将 UTF-8 指定为
encoding属性。 -
@Berger 源代码在 RHEL 服务器上编译。在一篇文章中，我看到 linux 机器的默认编码是 UTF-8。我们有 ISO-8859-1 的等效编码吗？尝试您提到的选项是一个巨大的选择。作为一名构建工程师，我无法做到这一点，因为有许多具有相同编码的来源，我无法建议开发人员使用相同的选项。
-
我没有得到您更改为 UTF8 的内容和方式，是您的源代码还是什么？？
