Text Normalization

Transform text to normalized form, optionally mapping to lowercase and applying compatibility maps.

Usage
utf8_normalize(x, map_case = FALSE, map_compat = FALSE,
               map_quote = FALSE, remove_ignorable = FALSE)
Arguments
x

character object.

map_case

a logical value indicating whether to apply Unicode case mapping to the text. For most languages, this transformation changes uppercase characters to their lowercase equivalents.

map_compat

a logical value indicating whether to apply Unicode compatibility mappings to the characters, those required for NFKC and NFKD normal forms.

map_quote

a logical value indicating whether to replace curly single quotes and Unicode apostrophe characters with ASCII apostrophe (U+0027).

remove_ignorable

a logical value indicating whether to remove Unicode "default ignorable" characters like zero-width spaces and soft hyphens.

Details

utf8_normalize converts the elements of a character object to Unicode normalized composed form (NFC) while applying the character maps specified by the map_case, map_compat, map_quote, and remove_ignorable arguments.

Value

The result is a character object with the same attributes as x but with Encoding set to "UTF-8".
