Technically this returns the number of "code points", in a string. One
code point usually corresponds to one character, but not always. For example,
an u with a umlaut might be represented as a single character or as the
combination a u and an umlaut.
Usage
str_length(string)
Arguments
string
Input vector. Either a character vector, or something
coercible to one.
Value
A numeric vector giving number of characters (code points) in each
element of the character vector. Missing string have missing length.
See Also
stri_length which this function wraps.
Examples
str_length(letters)
str_length(NA)
str_length(factor("abc"))
str_length(c("i", "like", "programming", NA))
# Two ways of representing a u with an umlaut
u1 <- "u00fc"
u2 <- stringi::stri_trans_nfd(u1)
# The print the same:
u1
u2
# But have a different length
str_length(u1)
str_length(u2)
# Even though they have the same number of characters
str_count(u1)
str_count(u2)
