Getting "sed error - illegal byte sequence" (in bash)
提问by alt
Doing some stream editing to change the nasty Parallels icon. It's poorly developed and embedded into the app itself rather than being an image file. So I've located this sed command that has some good feedback:
进行一些流编辑以更改讨厌的 Parallels 图标。它的开发很差并且嵌入到应用程序本身中，而不是一个图像文件。所以我找到了这个 sed 命令，它有一些很好的反馈：
sudo sed -i.bak s/Parallels_Desktop_Overlay_128/Parallels_Desktop_Overlay_000/g /Applications/Parallels\ Desktop.app/Contents/MacOS/prl_client_app
It returns sed: RE error: illegal byte sequence
它返回 sed: RE error: illegal byte sequence
Can anyone explain what this means? What part of the command is the problem?
谁能解释一下这是什么意思？命令的哪一部分有问题？

Try setting the LANGenvironment variable (LANG=C sed ...) or use one of the binary sed tools mentioned here: binary sed replacement
尝试设置LANG环境变量 ( LANG=C sed ...) 或使用这里提到的二进制 sed 工具之一：二进制 sed 替换
Why the error?
为什么会出错？
Without LANG=Csed assumes that files are encoded in whatever encoding is specified in LANGand the file (being binary) may contain bytes which are not valid characters in LANG's encoding (thus you could get 'illegal byte sequence').
没有LANG=Csed 假设文件以指定的任何编码进行编码，LANG并且文件（二进制）可能包含在LANG' 编码中无效的字节（因此您可能会得到'非法字节序列'）。
Why does LANG=Cwork?
为什么LANG=C有效？
C just happens to treat all ASCII characters as themselves and non-ASCII characters as literals.
C 恰好将所有 ASCII 字符视为它们自己，将非 ASCII 字符视为文字。

LANG=Calone didn't do the trick for me but adding LC_CTYPE=Cas well solved it.
LANG=C独自一人并没有为我LC_CTYPE=C解决问题，但添加也解决了它。

In addition to LANG=Cand LC_CTYPE=C, I had to do LC_ALL=Cto get this to work.
除了LANG=Cand 之外LC_CTYPE=C，我还必须这样做LC_ALL=C才能使其正常工作。
LC_ALLoverrides all individual LC_*categories. Thus, the most robust approach is to use LC_ALL=C sed ...- no need to also deal with the other variables.
LC_ALL覆盖所有单独的LC_*类别。因此，最稳健的方法是使用LC_ALL=C sed ...——无需同时处理其他变量。

I managed to do it by running:
我设法通过运行来做到这一点：
unset LANG
before the sedcommand.
sed命令之前。
Not sure what I've done or why it works but it did.
不知道我做了什么或为什么它有效，但确实如此。
