从CSV 11答案中删除非ASCII字符

I am trying to manipulate a text file and remove non-ASCII characters from the text. I don't want to remove the line. I only want to remove the offending characters. I am trying to get the following expression to work:

我试图操纵文本文件并从文本中删除非ASCII字符。我不想删除该行。我只想删除有问题的字符。我试图让以下表达式工作：

sed '/[\x80-\xFF]/d'

sed'/ [\ x80- \ xFF] / d'

The suggested solutions may fail with specific version of sed, e.g. GNU sed 4.2.1.

建议的解决方案可能会因特定版本的sed而失败，例如： GNU sed 4.2.1。

Using tr:

使用tr：

tr -cd '[:print:]' < yourfile.txt

This will remove any characters not in [\x20-\x7e].

这将删除[\ x20- \ x7e]中没有的任何字符。

If you want to keep e.g. line feeds, just add \n:

如果你想保持，例如换行，只需添加\ n：

tr -cd '[:print:]\n' < yourfile.txt

If you really want to keep all ASCII characters (even the control codes):

如果你真的想保留所有ASCII字符（甚至是控制代码）：

tr -cd '[:print:][:cntrl:]' < yourfile.txt

This will remove any characters not in [\x00-\x7f].

这将删除不在[\ x00- \ x7f]中的任何字符。
