如何使用scala删除文件中的特殊字符？

import java.io.{FileWriter, BufferedReader, FileReader}

object RemoveSpecialCharacters {
  def main(args: Array[String]): Unit = {
    val filePath = "path/to/your/file.txt"
    val outputFile = "path/to/your/output/file.txt"
    removeSpecialCharacters(filePath, outputFile)
  }

  def removeSpecialCharacters(inputFilePath: String, outputFilePath: String): Unit = {
    val fileReader = new FileReader(inputFilePath)
    val bufferedReader = new BufferedReader(fileReader)
    val stringBuilder = new StringBuilder()
    var line: String = null

    try {
      while ({line = bufferedReader.readLine(); line != null}) {
        val cleanedLine = line.replaceAll("[^a-zA-Z0-9\\s]", "")
        stringBuilder.append(cleanedLine).append("\n")
      }
    } finally {
      if (bufferedReader != null) bufferedReader.close()
      if (fileReader != null) fileReader.close()
    }

    val fileWriter = new FileWriter(outputFilePath)
    try {
      fileWriter.write(stringBuilder.toString())
    } finally {
      if (fileWriter != null) fileWriter.close()
    }
  }
}
