推荐答案

验证名称的正确方法是:

The correct way to validate names is:

1. 接受任何和所有可能的 Unicode 字符.
2. 拒绝长度为 0 的输入.
3. 确保结果中至少有一个不是\pM、\pZ和\pC类型的字符；即，既不是组合标记、分隔符之一，也不是其他(通常是控制)字符.像 [^\pM\pC\pZ] 这样的字符类就足够了.

1. Accept any and all possible Unicode characters.
2. Reject inputs of length 0.
3. Make sure the result has at least one character that is neither of type \pM, \pZ, nor \pC; i.e., is neither one of the combining marks, separators, nor other (usually control) characters. A character class like [^\pM\pC\pZ] should suffice.

那里:尽可能简单.不过，您可能需要 Ruby 1.9 才能正确执行此操作.

There: easy as can be. You will probably need Ruby 1.9 to do this properly, though.
