regular expression for French characters
提问by nextu
I need a function or a regular expression to validate strings which contain alpha characters (including French ones), minus sign (-), dot (.) and space (excluding everything else)
我需要一个函数或正则表达式来验证包含字母字符（包括法语字符）、减号 (-)、点 (.) 和空格（不包括其他所有内容）的字符串
Thanks
谢谢

/^[a-zàa?éèê?????ùü???? .-]*$/i
Use of /ifor case-insensitivity to make things simpler. If you don't want to allow empty strings, change *to +.
使用/ifor 不区分大小写使事情变得更简单。如果您不想允许空字符串，请更改*为+.

The character class I've been using is the following:
我一直在使用的字符类如下：
[\wà-üà-?où-???]. This covers a slightly larger character set than only French, but excludes a large portion of Eastern European and Scandinavian diacriticals and letters that are not relevant to French. I find this a decent compromise between brevity and exclusivity.
[\wà-üà-?où-???]. 这涵盖了比仅法语稍大的字符集，但排除了大部分与法语无关的东欧和斯堪的纳维亚变音符号和字母。我发现这是简洁性和排他性之间的一个不错的妥协。
To match/validate complete sentences, I use this expression:
[\w\s.,!?:;&#%''"()??à-üà-?où-???], which includes punctuation and French style quotation marks.
为了匹配/验证完整的句子，我使用以下表达式：
[\w\s.,!?:;&#%''"()??à-üà-?où-???]，其中包括标点符号和法式引号。

[\w .-]should suffice, but you'll need to have \wconsider the locale and/or put it into Unicode mode, so \wmatches what Unicode defines as alpha-numeric characters. How to do that in PHP is probably just a Google away.
[\w .-]应该足够了，但是您需要\w考虑语言环境和/或将其置于 Unicode 模式，以便\w匹配 Unicode 定义为字母数字字符的内容。如何在 PHP 中做到这一点可能只是谷歌。

This might suit:
这可能适合：
/^[ a-zA-Z\xBF-\xFF\.-]+$/
It lets a few extra chars in, like ÷, but it handles quite a few of the accented characters.
它允许输入一些额外的字符，例如 ÷，但它可以处理相当多的重音字符。

/[A-Za-z-\.\s]/ushould work.. /u switch is for UTF-8 encoding
/[A-Za-z-\.\s]/u应该可以工作.. /u 开关用于 UTF-8 编码
