fread quote = "\"" does not work as expected

[jan-swissre]

utils::read.csv seems to be expected behavior here

body = 'a,b
1,"a unquoted a"
2,"b ""quoted"" b"
'
data.table::fread(body)
#       a              b
#   <int>         <char>
#1:     1   a unquoted a
#2:     2 b ""quoted"" b
data.table::fread(body, quote = "\"")
#       a              b
#   <int>         <char>
#1:     1   a unquoted a
#2:     2 b ""quoted"" b

writeLines(body, f<-tempfile())
utils::read.csv(f, quote = "\"") ## default quote
#  a            b
#1 1 a unquoted a
#2 2 b "quoted" b
