从 Ruby 中的字符串中删除非 UTF 字符?

问题描述

如何从 ruby​​ 字符串中删除非 UTF8 字符?我有一个字符串，其中包含例如xC2".我想从字符串中删除该字符，使其成为有效的 UTF8.

How do I delete non-UTF8 characters from a ruby string? I have a string that has for example "xC2" in it. I want to remove that char from the string so that it becomes a valid UTF8.

这个:

text.gsub!(/\xC2/, '')

返回错误:

incompatible encoding regexp match (ASCII-8BIT regexp with UTF-8 string)

我也在看 text.unpack('U*') 和 string.pack，但没有找到任何地方.

I was looking at text.unpack('U*') and string.pack as well, but did not get anywhere.

推荐答案

您可以为此使用 encode.text.encode('UTF-8', :invalid => :replace, :undef => :replace)

You can use encode for that.text.encode('UTF-8', :invalid => :replace, :undef => :replace)
