R默认编码为UTF-8 [英] R default encoding to UTF-8

问题描述

如何在library\base\R中配置Rprofile，以使默认字符集为UTF-8而不是本机。

How to configure Rprofile in 'library\base\R' so that default charset is UTF-8 rather than native.

配置为行

options(encoding = "native.enc")

我想替代native.enc，我们需要放置UTF-8相关的值。

I suppose in place of native.enc, we need to put UTF-8 relevant value.

推荐答案

从R 3.0.0开始，接受编码UTF-8-BOM进行读取，并删除字节顺序标记（通常用于Microsoft应用程序生成的文件和网页）。如果需要BOM（不推荐），写入时应明确书写，例如通过writeChar（\\\，con，eos = NULL）或writeBin（as.raw（c（0xef，0xbb，0xbf）），binary_con）

As from R 3.0.0 the encoding "UTF-8-BOM" is accepted for reading and will remove a Byte Order Mark if present (which it often is for files and webpages generated by Microsoft applications). If a BOM is required (it is not recommended) when writing it should be written explicitly, e.g. by writeChar("\ufeff", con, eos = NULL) or writeBin(as.raw(c(0xef, 0xbb, 0xbf)), binary_con)

编码名称utf8，mac和macroman不可移植，并且不支持所有当前的R平台。 UTF-8是便携式的，macintosh是Mac Roman的官方（最受欢迎的）名称。

Encoding names "utf8", "mac" and "macroman" are not portable, and not supported on all current R platforms. "UTF-8" is portable and "macintosh" is the official (and most widely supported) name for ‘Mac Roman’.
