使用 twitteR R 包进行西里尔文推文的编码问题 [英] encoding issue using twitteR R package for Cyrillic tweets
问题描述
我想通过 twitteR 包解析西里尔文推文.
I want to parse Cyrillic tweets via twitteR package.
我运行这个简单的代码来获取最后 5 条推文:
I run this simple code to get last 5 tweets:
> library("twitteR")
> tweets=userTimeline(user="ru_mts",n=100)
> tweets[1:5]
输出如下.我应该怎么做才能使用它?肯定有一些与编码有关的东西.谢谢.
The output is below. What should I do to get it usable? There is definitely something with encoding. Thanks.

推荐答案
问题实际上存在于 RJSONIO::fromJSON 和 RCurl::getURL 中，它们正在/正在剥离 'UTF-8' 编码.
The issue actually resides with RJSONIO::fromJSON and RCurl::getURL which are/were striping out the 'UTF-8' encoding.
RJSONIO::fromJSON() 不用于保留编码，但如果您更新到 RJSONIO 0.96-0 会保留.
RJSONIO::fromJSON() didn't used to preserve the encoding but does if you update to RJSONIO 0.96-0.
Duncan 目前正在研究 RCurl::getURL 的编码问题(它使用正确的编码来创建字符向量元素，但随后发生了一些奇怪的事情).
Duncan is currently looking into the encoding issue for RCurl::getURL (it uses the correct encoding to create the character vector element but then something odd happens).
简短的回答是将 RJSONIO 更新到 0.96-0，然后在下一个版本发布并修复时更新 RCurl.
Short answer is to update RJSONIO to 0.96-0 and then update RCurl when the next version is released with a fix.
