                </dependencies>
            </plugin>
```

## What is the smallest, simplest way to reproduce the problem?

- The file encoding is set to Windows-31J (MS932).

```java
package org.example;

public class TestClass {
    public void test() {
        // TODO: メソッド実行
        return;
    }
}
```

## What did you expect to see?

```java
package org.example;

public class TestClass {
    private void test() {
        // TODO: メソッド実行
        return;
    }
}
```

## What did you see instead?

```java
package org.example;

public class TestClass {
    private void test() {
        // TODO: �
```

## Context
- As a Japanese developer working on a legacy system migration, I am planning to use OpenRewrite.
- I am unable to change the file encoding of the target files, which are encoded in Windows-31J (MS932).
- The issue does not occur during JUnit test execution; the test completes successfully. However, it fails when using the Maven plugin.
```
mvn -X rewrite:run
```
