你的三个答案并没有帮助我解决这个问题。当我使用hexa值时，它给出如下

$echo-e“compilein\xe2\x80\x99我的程序”

compilein–我的程序

问题是，当我在unix中粘贴撇号时，它显示为“.”

您可以使用以下命令使用

sed查找replace
（请注意，您需要转义特殊字符）
如果要就地编辑文件，可以使用以下语法（请注意，a.txt
的内容将在执行命令后修改）
'
字符与'
字符不同。要更清楚地了解这一点，请检查其十六进制值：
echo -n ’ | hexdump -C
00000000  e2 80 99                                          |...|
00000003
echo -n \' | hexdump -C
00000000  27                                                |'|
00000001

现在，当使用sed
或类似工具在序列中替换时，可以通过其十六进制值来识别”
：
echo -e "compilin\xe2\x80\x99 my program"
compilin’ my program
echo -e "compilin\xe2\x80\x99 my program" | sed "s|\xe2\x80\x99|'|"
compilin' my program

仅当撇号字符出现在文本中时，它才会替换撇号字符。在您的情况下，只需将文件名作为第二个参数传递给sed
，就完成了：
sed -i "s|\xe2\x80\x99|'|" HAllResponses_11004_1.txt

或者只是：
sed -i "s|’|'|" HAllResponses_11004_1.txt

您可以使用cat-vet查看unix中的控制字符，然后使用sed替换这些字符。在下面的示例中，cat-vet将（'）显示为（M-^R），可以使用sed轻松替换
原始文件：
My file contains an apostrophe (’). I am able to see this character if the file opens in Windows but not able to see it if the file opens in Unix. But I need to use that file once after removing that character.
I can't use windows to remove the character manually. My servers are Unix so I need to remove the character at that point. I have tried the following but it didn't work.

在Unix中使用cat-vet显示的控制字符：
/home/temp_files > cat -vet SO.txt
My file contains an apostrophe (M-^R). I am able to see this character if the file opens in Windows but not able to see it if the file opens in Unix. But I need to use that file once after removing that character.$
I can't use windows to remove the character manually. My servers are Unix so I need to remove the character at that point. I have tried the following but it didn't work.$

替换为sed：
/home/temp_files > cat -vet SO.txt  | sed 's/M-^R//g'
My file contains an apostrophe (). I am able to see this character if the file opens in Windows but not able to see it if the file opens in Unix. But I need to use that file once after removing that character.$
I can't use windows to remove the character manually. My servers are Unix so I need to remove the character at that point. I have tried the following but it didn't work.$
