Answer 1

如果你只想保留基本的 ASCII 字符，你可以尝试这样的事情：

\n

  var c =\n      "Maintain central project files (hard copy and electronic) for administration.\xc3\xa2\xc2\xa2Perform a wide variety of administrative duties";\n  var clean = c.replaceAll(RegExp(r'[^A-Za-z0-9().,;?]'), ' ');\n  print(clean);\n

\n

你得到：

\n

Maintain central project files (hard copy and electronic) for administration.  Perform a wide variety of administrative duties\n

\n

调整正则表达式以包含更多或更少的字符，具体取决于您想要的清理量（假设您可以删除所有标点符号等......）
