How to find french UTF-8 accent character in R with the simple character using str_detect?

I need to find accented characters with the simple character. For example: "é","è" or "ê" with e in French Canadian, UTF-8. 

 library(tidyverse)

 Sys.setlocale(locale = "fr_CA.UTF-8")
 a <- c("Léger", "leger")

 str_detect(a, regex("leger", ignore_case=T))
 ## [1]  FALSE  TRUE

 str_detect(a, coll("leger", ignore_case=T, locale = "fra"))
 ## [1] FALSE  TRUE

The results of this code should be TRUE, TRUE.

You can convert the input string to just use ASCII characters then do the match on that. For example

str_detect(iconv(a, to='ASCII//TRANSLIT'),regex("leger", ignore_case=T))
# [1] TRUE TRUE
