问题描述

我目前在处理 amazon api 的结果时遇到问题.

i am currently having trouble with results from the amazon api.

该服务返回一个包含 unicode 字符的字符串:Mac 上的 Learn ObjectivexE2x80x93C(学习系列)

the service returns a string with unicode characters: Learn ObjectivexE2x80x93C on the Mac (Learn Series)

使用 ruby 1.9.1 甚至无法处理字符串:

with ruby 1.9.1 the string could not even been processed:

REXML::ParseException: #<Encoding::CompatibilityError: incompatible encoding regexp match (UTF-8 regexp with ASCII-8BIT string)>

...

Exception parsing

Line: 1

Position: 1636

Last 80 unconsumed characters:

Learn Objective–C on the Mac (Learn Series)

推荐答案

作为例外点，您的字符串是 ASCII-8BIT 编码的.您应该更改编码.有一个长篇故事，但如果您对快速解决方案感兴趣，只需force_encoding 在你做任何处理之前:

As the exception points, your string is ASCII-8BIT encoded. You should change the encoding. There is a long story about that, but if you are interested in quick solution, just force_encoding on the string before you do any processing:

s = "Learn ObjectivexE2x80x93C on the Mac"
# => "Learn ObjectivexE2x80x93C on the Mac"
s.encoding
# => #<Encoding:ASCII-8BIT>
s.force_encoding 'utf-8'
# => "Learn Objective–C on the Mac"
