Encoding information

The encoding function returns "ASCII" if the entire value consists of ASCII symbols only, and works identically to Encoding() otherwise. The all_utf8 function is an efficient variant of all(encoding(x) %in% c("ASCII", "UTF-8")).

encoding(x)

all_utf8(x)

Arguments

x	A character vector.

Examples

encoding("a")
#> [1] "ASCII"
encoding("\u00fc")
#> [1] "UTF-8"
all_utf8(enc2utf8(c("a", "\u00fc")))
#> [1] TRUE

# Platform-dependent:
all_utf8(enc2native(c("a", "\u00fc")))
#> [1] TRUE
