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"'.

Examples:

     ## Not run: 
     ## will only display in some locales and fonts
     intToUtf8(0x03B2L) # Greek beta
     ## End(Not run)
