Question

字符集编码格式的新功能。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characterSet格式更改为UTF-8，从那时开始编译问题。

引发的错误是：

[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>

我的一个有问题的课程中包含以下代码：

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characterset更改为UTF-16，但这次它抛出了不同的错误：

有人可以为此提供帮助吗？

谢谢和问候，

我在编码级别上尝试了多种方法。没有任何效果。

最后我尝试了Berger建议，将源代码编码格式更改为UTF-8然后使用UTF-8构建一切正常。我唯一需要注意的是项目中使用的特殊字符。一旦项目级别的编码被更改，特殊字符就会更改为??符号。我需要转换所有这些？到实际的特殊字符。这是我需要花费的唯一努力。对于开发人员而言，这可能是一个混乱的情况，但由于这是开发人员/每个项目的一次性活动，这应该没问题。

感谢Berger的建议。
