如何在Windows下显示带有Unicode字符的消息/警告/错误? [英] How to display a message/warning/error with Unicode characters under Windows?

问题描述

我有一条包含Unicode字符的消息(或警告或错误). (字符串具有UTF-8编码.)

I have a message (or warning or error) containing Unicode characters. (The string has UTF-8 encoding.)

x <- "\u20AC \ub124" # a euro symbol, and Hangul 'ne'
## [1] "€ 네"
Encoding(x)
## [1] "UTF-8"

在Linux下，如果语言环境为UTF-8(l10n_info()$`UTF-8`返回TRUE)，则会在消息中显示OK.

Under Linux, this prints OK in a message if the locale is UTF-8 (l10n_info()$`UTF-8` returns TRUE).

我可以通过例如

devtools::with_locale(
  c(LC_CTYPE = "en_US.utf8"),
  message(x)  
)
## € 네

在Windows下，没有UTF-8语言环境，因此我找不到强制执行正确打印的等效方法.例如，在美国语言环境中，韩文字符无法正确显示.

Under Windows there are no UTF-8 locales, so I can't find an equivalent way to enforce correct printing. For example, with a US locale, the Hangul character doesn't display properly.

devtools::with_locale(
  c(LC_CTYPE = "English_United States"),
  message(x)  
)
## € <U+B124>

存在一个相关问题，在Windows下打印数据帧时Unicode字符无法正确显示.那里的建议是将语言环境设置为中文/日文/韩文.这在这里不起作用.

There's a related problem with Unicode characters not displaying properly when printing data frames under Windows. The advice there was to set the locale to Chinese/Japanese/Korean. This does not work here.

devtools::with_locale(
  c(LC_CTYPE = "Korean_Korea"),
  message(x)  
)
## ¢æ ³×   # equivalent to iconv(x, "UTF-8", "EUC-KR")

如何获取UTF-8消息，警告和错误以在Windows下正确显示?

How can I get UTF-8 messages, warnings and errors to display correctly under Windows?

推荐答案

我注意到R中的Sys.setlocale()函数的帮助说:"LC_MESSAGES"在不支持消息的系统上为"C"翻译，，并且Windows上不支持.

I noticed that the help for the function Sys.setlocale() in R says this: "LC_MESSAGES" will be "C" on systems that do not support message translation, and is not supported on Windows.

对我来说，这听起来像在任何Windows版本上都无法修改R消息/错误的字符表示形式...

To me this sounds like modifying character representation for R messages/errors can't be done on any Windows version...
