utf8Conversion: Convert Integer Vectors to or from UTF-8-encoded Character Vectors
Description
Conversion of UTF-8 encoded character vectors to and from integer vectors.
Usage
utf8ToInt(x)
intToUtf8(x, multiple = FALSE)
Arguments
x
object to be converted.
multiple
logical: should the conversion be to a single
character string or multiple individual characters?
Value
Unicode defines a name and a number of all of the glyphs it
encompasses: the numbers are called code points: they run from
0 to 0x10FFFF. utf8ToInt converts a length-one character string encoded in
UTF-8 to an integer vector of Unicode code points. As from R 3.2.1
it checks validity of the input and returns NA if it is invalid. intToUtf8 converts a numeric vector of Unicode code points
either to a single character string or a character vector of single
characters. (For a single character string 0 is silently
omitted: otherwise 0 is mapped to "". Non-integral
numeric values are truncated to integers.) The Encoding
is declared as "UTF-8". NA inputs are mapped to NA output.
Details
These will work in any locale, including on platforms that do not
otherwise support multi-byte character sets.
