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")
