Hi there,

I am intending to get the length of an UTF-8 string which contains some Japanese characters (let's say, rstr) in R language. I try to use the nchar(rstr) to get its length, however, it returns the "NA" for it contains some multi-byte characters.

Is there any alternatives to return the length of this rstr?

Any suggestion is appreciated.
