I'm using a simple Javascript regular expression to validate people's names. However, I do not want to allow a user to enter accented characters like ã, ä, õ, ö, etc. I am aware that these can actually be valid characters in a name, but for my exercise, I need to be able to filter them out.
我正在使用一个简单的Javascript正则表达式来验证人们的名字。但是，我不想让用户输入重音字符，如ã，ä，õ，ö等。我知道这些字符实际上可以是名字中的有效字符，但对于我的练习，我需要能够过滤掉它们。
My current regex:
我现在的正则表达式：
^[a-zA-Z]+('|-|.|)[a-zA-Z\s]+$
This matches accented characters as well. How do I modify this regex so that it doesn't match names with accents (or any Unicode character, for that matter)?
这也匹配重音字符。如何修改此正则表达式，使其与带重音的名称（或任何Unicode字符）不匹配？

Remove ., because . match any character. That could cause matching accented character.
删除。，因为。匹配任何角色。这可能会导致匹配的重音字符。
^[a-zA-Z]+('|-)[a-zA-Z\s]+$
or escape . if you mean literal dot.
或逃避。如果你的意思是字面点。
^[a-zA-Z]+('|-|\.)[a-zA-Z\s]+$

To match a single character it's better to use a class [...], not a group with alternatives (...|...):
要匹配单个字符，最好使用类[...]，而不是具有替代项的组（... | ...）：
^[a-zA-Z]+['.-][a-zA-Z\s]+$
Note that this is not 100% accurate, since it validates things like foo.bar etc.
请注意，这不是100％准确，因为它验证了诸如foo.bar之类的东西。
