utf8-package {utf8}

The utf8 Package

Description

UTF-8 Text Processing

Details

Functions for manipulating and printing UTF-8 encoded text:

• as_utf8 attempts to convert character data to UTF-8, throwing an error if the data is invalid;

• utf8_valid tests whether character data is valid according to its declared encoding;

• utf8_normalize converts text to Unicode composed normal form (NFC), optionally applying case-folding and compatibility maps;

• utf8_encode encodes a character string, escaping all control characters, so that it can be safely printed to the screen;

• utf8_format formats a character vector by truncating to a specified character width limit or by left, right, or center justifying;

• utf8_print prints UTF-8 character data to the screen;

• utf8_width measures the display width of UTF-8 character strings (many emoji and East Asian characters are twice as wide as other characters);

• output_ansi and output_utf8 test for the output connections capabilities.

For a complete list of functions, use library(help = "utf8").
