如果函数源于stringr，则Stringi/stringr模式的行为不同

我现在正在使用

stringi

软件包一段时间，一切正常

我最近想在一个函数中放入一些正则表达式，并将该函数存储在一个单独的文件中。如果函数是从脚本中加载的，那么代码就可以正常工作，但是当它是源代码时，我没有得到预期的结果

以下是重现问题的代码：

clean <- function(text){
  stri_replace_all_regex(str = text, 
                         pattern = "(?i)[^a-zàâçéèêëîïôûùüÿñæœ0-9,\\.\\?!']",
                         replacement = " ")
}
text <- "A sample text with some french accent é, è, â, û and some special characters |, [, ( that needs to be cleaned."
clean(text) # OK
[1] "A sample text with some french accent é, è, â, û and some special characters  ,  ,   that needs to be cleaned."
source(clean.r)
clean(text) # KO
[1] "A sample text with some french accent  ,  ,  ,   and some special characters  ,  ,   that needs to be cleaned."

首先尝试将文本转换为ASCII。这将更改字符，并且在R中生成函数时可能允许相同的行为

text我也有类似的问题。我认为这与文件来源时如何读取特殊字符有关。我的文本包含“；”而你的文本包含法语重音“é，è，è”。
