用字符串中的变音符号替换字符 [英] Replacing characters with diacritics in a string

问题描述

我想去掉一些特殊字符.

Im trying to get rid of some special characters.

在这种情况下，瑞典语 ÅÄÖ 和 åäö.为什么这不起作用?

In this case Swedish ÅÄÖ and åäö. Why is this not working?

结果应该是 AAOaao 但我得到 ÅÄÖåäO?

The result should be AAOaao but I get ÅÄÖåäO?

$stringX = "ÅÄÖåäö"

$stringX = ($stringX -replace "Å$","A")
$stringX = ($stringX -replace "Ä$","A")
$stringX = ($stringX -replace "Ö$","O")
$stringX = ($stringX -replace "å$","a")
$stringX = ($stringX -replace "ä$","a")
$stringX = ($stringX -replace "ö$","o")

"Result = $stringX"

推荐答案

哦！你离得太近了！删除 "Å$" 中的 $ 符号对我有用.

Oh! You were so close! Removing the $ sign in the "Å$" worked for me.

自己试试...

$stringX = "ÅÄÖåäö"

   $stringX = ($stringX -replace "Å","A")
   $stringX = ($stringX -replace "Ä","A")
   $stringX = ($stringX -replace "Ö","O")
   $stringX = ($stringX -replace "å","a")
   $stringX = ($stringX -replace "ä","a")
   $stringX = ($stringX -replace "ö","o")

  "Result = $stringX"

正如注释中所指出的，$ 表示正则表达式中字符串的结尾.由于您的示例中只有最后一个ö"满足这一点，因此它是唯一一个被替换的.

As pointed out in the comments $ means the end of the string in regex. Since only the final "ö" satisfies this in your sample, it was the only one getting replaced.

还指出，-replace 不区分大小写不敏感，因此您已经有效地复制了您的工作.如果你想替换一切，你只需要

Also pointed out, -replace is case-insensitive so you've effectively duplicated your work. If you want to replace everything, you only need

   $stringX = ($stringX -replace "Å","A")
   $stringX = ($stringX -replace "Ä","A")
   $stringX = ($stringX -replace "Ö","O")

如果您只需要替换大写或小写，则使用-creplace.

If you need to only replace either upper or lower case, then use the -creplace.

   # Only replace the upper case letters...
   $stringX = ($stringX -creplace "Å","A")
   $stringX = ($stringX -creplace "Ä","A")
   $stringX = ($stringX -creplace "Ö","O")
