##### Usage
localeToCharset(locale = Sys.getlocale("LC_CTYPE"))
##### Arguments
locale

character string naming a locale.

##### Details

The operation differs by OS. A Windows locale is specified like "English_United Kingdom.1252". The final component gives the codepage, and this defines the encoding. Locale names are normally like es_MX.iso88591. If final component indicates an encoding and it is not utf8 we just need to look up the equivalent encoding name. Otherwise, the language (here es) is used to choose a primary or fallback encoding.

In the C locale the answer will be "ASCII".

##### Value

A character vector naming an encoding and possibly a fallback single-encoding, NA if unknown.

##### Note

The encoding names are those used by libiconv, and ought also to work with glibc but maybe not with commercial Unixen.

Sys.getlocale, iconv.
