从颤振/飞镖的字符串中删除不可打印的字符

Question

如何从Flutter / Dart中的字符串中删除不可打印的字符。

var c ="Maintain central project files (hard copy and electronic) for administration.â¢Perform a wide variety of administrative duties"

感谢您的帮助

Answer 1

如果您只想保留基本的ascii字符，则可以尝试如下操作：

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

您会得到：

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

调整正则表达式以包含更多或更少的字符，具体取决于您希望清除的次数（例如，您可以删除所有标点符号等）
