Ruby 如何解码svg数据uri（非base64）,ruby,svg,utf-8,decoding,data-uri,Ruby,Svg,Utf 8,Decoding,Data Uri,我有svg数据uri： "data:image/svg+xml;charset=utf8,%3Csvgxmlns='http://www.w3.org/2000/svg'width='18'height='36'viewBox='001836'%3E%3Cpathd='M15.70714.293l-2.82-2.82C13.58510.493149.296148c0-3.314-2.686-6-6-6S24.68628s2.686666c1.29602.492-.4153.473-1.113l2

我有svg数据uri：

请帮我把它解码成svg文件。我使用'data_uri'gem解码base64数据uri没有问题，但是如果我尝试使用优化的url编码，我有一个错误：

ArgumentError:未知编码名称-utf8

这看起来像是URL编码的：
