Convert 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

Details

These will work in any locale, including on machines that do not otherwise support multi-byte character sets.

Value

utf8ToInt converts a length-one character string encoded in UTF-8 to an integer vector of (numeric) UTF-8 code points.

intToUtf8 converts a vector of (numeric) UTF-8 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".

As from R 2.11.0 NA inputs are mapped to NA output.
