If you still want to obtain the actual codes, you will be able to get
the number using utf8ToInt from package base or AsciiToInt from
package sfsmisc. By default, the integer codes will be printed in base
10, though.
A roundabout way, assuming your are on a *nix system, would be to
dump() cnt_str into a file, say tmp.txt, then run in a shell (or using
system() ) something like
sed --in-place 's/\\//g' tmp.txt
to remove the slashes, then use
cnt_str_new = read.table("tmp.txt")
in R to get the codes back in. I'll let you iron out the details.
