Question

我试图读取yml文件并将其转换为对象以在yml文件中进行更改，但是在Linux服务器中使用ISO_8859_1进行转换时遇到以下异常。

例外：

const array: ElementArray = [
    {
        id: 'cars',
        options: [
            {
                label: 'One',
                value: 1,
            },
            {
                label: 'Two',
                value: 2,
            }
        ] as {
    label: string
    value: number
}[]
    },
    {
        id: 'year',
        options: [
            {
                label: '70',
                value: '1970',
            },
            {
                label: 'Unknown',
                value: null,
            }
        ] as {
    label: string
    value: null | string
}[]
    }
]

Yaml内容：

StringBuilder contentBuilder = new StringBuilder();
String originalFile = "..path";
try (Stream<String> stream = java.nio.file.Files.lines(Paths.get(originalFile), StandardCharsets.ISO_8859_1)) {
            stream.forEach(s -> contentBuilder.append(s).append("\n"));
        }
        
        Object obj = yamlReader.readValue(contentBuilder.toString(), Object.class);

根据请求添加了Yaml内容以及异常详细信息和代码提取。

感谢您的帮助。

您可以看到here和here，此代码点对应于Windows-1252中的右引号字符，可能是因为该文件是在Windows系统中编辑的。

如异常所示，此代码点不受iso-8859-1或utf-8支持：请参见this page，以比较每种编码如何支持此字符和其他字符。 / p>

要解决您的问题，只需编辑文件并将其保存在iso-8859-1或utf-8编码中，以替换此字符即可，它应该可以工作。查看您的YAML文件，很可能是问题与您的错误can’t中的不同message单词有关。

YAMLException：不允许使用特殊字符
