我使用的是Ruby 2.3的Rails 4.2.7。我有这条线
words = line.split(/s+/)
在下面产生错误

该线包含一个重音" A"，我认为这会导致问题。是否有一种方法可以自动检测编码，然后再应用拆分。数据源自网络，但我想尽可能地保留角色与在线显示的角色。
如果您不知道编码是什么，则很难保持您的重音字符。这个：
words = line.encode("UTF-8", :invalid => :replace, :undef => :replace, :replace => "?").split(/s+/)
将用?替换它们，并防止您的分裂丢弃错误。
您是否知道编码可能是什么？iso-8859-1也许？
