Regular Expression to allow french text as well as english text?
提问by Suvankar Bhattacharya
I want to use a regular expression which will allow
我想使用一个正则表达式，它将允许
- English text which does not have a special character.
- French Text which does not have a special character.
- 没有特殊字符的英文文本。
- 没有特殊字符的法语文本。
It will always disallow special characters like @, #, % etc... in both the language.
它将始终禁止在这两种语言中使用特殊字符，如 @、#、% 等。
I have tried with the below code:
我已尝试使用以下代码：
if (this.value.match(/[^a-zA-Z0-9 ]/g)) {
this.value = this.value.replace(/[^a-zA-Z0-9 ]/g, '');
}
It works fine with english text, but the problem is when I provide a french text like éléphant, it considers the french characters as special character, and deletes the french characters. so éléphant becomes lphant.
它适用于英文文本，但问题是当我提供像 éléphant 这样的法语文本时，它会将法语字符视为特殊字符，并删除法语字符。所以 éléphant 变成了 lphant。
Is there any way to allow the french characters inside the regular expression?
有没有办法允许正则表达式中的法语字符？
Thanks a lot in advance.
非常感谢。

Most simplified solution:
最简化的解决方案：
/[^a-zA-Zà-?]/
(or)
（或者）
/[\wà-?]/ // Note: This will allow "_" also
Any of the above regular expression will work in your case.
上述任何正则表达式都适用于您的情况。

I would suggest normalizingstring before replacing chars.
我建议在替换字符之前标准化字符串。
This example is a JAVA normalization, but maybe this examplecould help you with javascript
这个例子是一个 JAVA 规范化，但也许这个例子可以帮助你使用 javascript
String string = "éléphante";
string = Normalizer.normalize(string, Normalizer.Form.NFD);
string = string.replaceAll("[^\p{ASCII}]", "");
System.out.println(string.replaceAll("[^a-zA-Z0-9 ]", ""));
