Does anyone know how I can get rid of hex A0 from a string?
提问by
I have the following string:
我有以下字符串：
Hello. ? Hello.
你好。? 你好。
If you look at the string in a hex editor it looks like this:
如果您在十六进制编辑器中查看字符串，它看起来像这样：
48 65 6C 6C 6F 2E 20 A0 20 20 48 65 6C 6C 6F 2E
48 65 6C 6C 6F 2E 20 A0 20 20 48 65 6C 6C 6F 2E
Note the A0in the middle. (This is the no-break space character).
注意A0中间的。（这是不间断空格字符）。
A0is breaking some JavaScript I am using so I would like to remove it when the string is being pre-processed by a PHP script.
A0正在破坏我正在使用的一些 JavaScript，所以我想在 PHP 脚本对字符串进行预处理时将其删除。
If I use the following code:
如果我使用以下代码：
$text = preg_replace("/\xA0/"," ", $text);
the A0gets replaced with 00which is also a troublesome character.
As you can see from the preg_replacefunction, it should be replace by a space, or 20.
将A0被替换为00这也是个麻烦人物。
从preg_replace函数中可以看出，它应该被替换为空格或20。
Do any of you know how I can get rid of this troublesome A0character?
你们有谁知道我怎样才能摆脱这个麻烦的A0角色吗？
Thank you.
谢谢你。
EDIT: I am using Windows-1252 and cannot switch to UTF-8. This won't be a problem if you are using UTF-8...
编辑：我使用的是 Windows-1252，无法切换到 UTF-8。如果您使用的是 UTF-8，这将不是问题...

I figured out a solution:
我想出了一个解决方案：
First convert the encoding type, and then do the replace:
首先转换编码类型，然后进行替换：
$text = mb_convert_encoding($text, "Windows-1252", "UTF-8");
$text = preg_replace("/\xA0/"," ", $text);
