多操作系统上的RMarkdown utf-8错误

问题描述

在多个操作系统上使用RMarkdown时遇到问题.

We have a problem using RMarkdown on multiple operating systems.

最初，在Linux系统(Ubuntu 12.04 LTS)上创建一个.Rmd文件，然后将其推送到GitHub存储库.

Initially, an .Rmd file is created on a Linux system (Ubuntu 12.04 LTS) and then pushed to a GitHub repo.

在此系统上，可以对其进行编译(编织")而没有问题.

It can be compiled ("knitted") without problems on this system.

然后在安装了RStudio的Windows 7计算机上将其拉出.

It is then pulled on a Windows 7 machine with RStudio installed.

在尝试编译时，出现以下错误:

There, when trying to compile, the following error shows up:

Error in yaml::yaml.load(front_matter) : 
  Reader error: invalid leading UTF-8 octet: #FC at 66
Calls: <Anonymous> -> parse_yaml_front_matter -> <Anonymous> -> .Call
Execution halted

1. 在Windows系统上创建另一个.Rmd文件时，它可以正常工作.
2. 在Windows系统上创建另一个.Rmd文件，并将除有问题的"文件的前几行以外的所有内容复制到另一个.Rmd文件，并编译该文件时，它可以正常工作.

我在两个操作系统上都以十六进制(在Sublime中)比较了两个文件:它们完全相同.

I compared both files in HEX (in Sublime) on both operating systems: They are EXACTLY the same.

其他人以前见过该错误吗?

Has somebody else seen that error before?

更新:根据 http://www.endmemo.com/unicode/unicodeconverter.php

通常，Windows上的R，RStudio或knitr似乎都无法正确识别Unicode.当我在一个新的.Rmd文件中键入一些Umlauts并将其编织时，我得到诸如öää"的输出.在RStudio>工具>全局选项中，我将默认文本编码设置为"UTF-8".我也为R在RProfile.site文件(options(encoding="UTF-8"))中进行了此操作.

In general, it seems that Unicode is not correctly recognized by either R, RStudio or knitr on Windows. When I type in some Umlauts in a new .Rmd file, and knit it, I get output such as "öää". In RStudio > Tools > Global options, I set the Default text encoding to "UTF-8". And I also did that for R, in the RProfile.site file (options(encoding="UTF-8")).

更新2: library(rmarkdown); sessionInfo()给出

R version 3.1.2 (2014-10-31)

在Windows 7上，而在Ubuntu上是:

on Windows 7, whereas, on Ubuntu, it is:

我已经怀疑问题出在不同的地区...我该如何解决?

I already suspect the problem to be the diverging locale... how do I fix this?

推荐答案

对此我来晚了，但我通过将选项编码改回本机"解决了该问题:

I am extremely late to this, but I solved the issue by changing the options encoding back to "native":

options(encoding="native")

并将默认窗口编码更改为UTF-8(这打开了与其他程序的编码相关的其他问题的数量不可忽略的pandora框；因此，请谨慎对待).

And changing the default windows encoding to UTF-8 (which opened the pandora box of a non-negligible number of other issues related to the encoding of other programs; so, treat with caution).
