转换utf8代码点字符串，例如< U + 0161>到utf8 [英] convert utf8 code point strings like <U+0161> to utf8

问题描述

我有一个文本文件，其中包含Unicode字符的某种后备转换(尖括号中的Unicode代码点).所以它包含例如foo<U+017E>bar，应为foošbar". R中是否有一种简单的方法可以将这些字符转换为整个文件为UTF8?不幸的是，我在Windows上，找不到支持的UTF-8语言环境.

I have a text file which contains some kind of fallback conversions of Unicode characters (the Unicode code points in angle brackets). So it contains e.g. foo<U+017E>bar which should be "foošbar". Is there an easy way in R to convert the whole file to UTF8 with these characters converted? Unfortunately I am on Windows and can't find a supported UTF-8 locale.

推荐答案

也许:

library(stringi)
library(magrittr)

"foo<U+0161>bar and cra<U+017E>y" %>% 
  stri_replace_all_regex("<U\\+([[:alnum:]]+)>", "\\\\u$1") %>% 
  stri_unescape_unicode() %>% 
  stri_enc_toutf8()
## [1] "foošbar and cražy"

可能有效(我不需要在macOS上进行最后一次转换，但在Windows上则可以.)

may work (I don't need the last conversion on macOS but you may on Windows).
