stri_length: Count the Number of Characters

Description

This function returns the number of code points in each string.

Usage

stri_length(str)

Arguments

str

character vector

Value

• Returns an integer vector of the same length as str.

Details

Note that the number of code points is not the same as the `width` of the string when printed on the screen.

If a given string is in UTF-8 and has not been properly Unicode normalized (e.g. by stri_enc_nfc), this number may sometimes be misleading.

Missing values are handled properly, as opposed to the built-in nchar function. For `byte` encodings we get, as usual, an error.

Examples

stri_length(LETTERS)
stri_length(c('abc','123','\u0105\u0104'))
stri_length('\u0105') # length is equal to one, but...
stri_numbytes('\u0105') # just like here
stri_length(stri_enc_nfkd('\u0105')) # ...two code points (!)
