Comparing Latin characters with and without accents?

Hello:


       How can one convert Latin characters with to the corresponding 
characters without?  For example, I want to convert "?" to "u", similar 
to how tolower('U') returns "u".


       This can be done using chartr{base}, e.g., chartr('?', 'u', 
'Ra?l') returns "Raul".  However, I wondered if a simpler version of 
this is available.

iconv("?", "", "ASCII//TRANSLIT")

       Thanks,
       Spencer

A brief review identified two to "Convert to ASCII": ASCIIfy {gtools} 
and stri_enc_toascii {stringi}.  Neither of these did what I expected.

This appears to work:

iconv("?", "", "ASCII//TRANSLIT")

[1] "u"
