R: Convert to or from UTF-8-encoded Character Vectors

utf8Conversion {base} | R Documentation

## 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

`x` | object to be converted.
`multiple` | logical: should the conversion be to a single character string or multiple individual characters?

### 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.

### Examples

    ## will only display in some locales and fonts
