Arguments

string

Input vector. Either a character vector, or something coercible to one.

locale

Locale to use for comparisons. See stringi::stri_locale_list() for all possible options. Defaults to "en" (English) to ensure that default behaviour is consistent across platforms.

Other options used to control collation. Passed on to stringi::stri_opts_collator().

A character vector, usually shorter than string.
