localeToCharset: Select a Suitable Encoding Name from a Locale Name

Description

This functions aims to find a suitable coding for the locale named, by default the current locale, and if it is a UTF-8 locale a suitable single-byte encoding.

Usage

localeToCharset(locale = Sys.getlocale("LC_CTYPE"))

Arguments

locale

character string naming a locale.

Value

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

Details

The operation differs by OS.

On Windows,: a locale is specified like "English_United Kingdom.1252". The final component gives the codepage, and this defines the encoding.
On Unix-alikes:: 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".

Examples

Run this code

# NOT RUN {
localeToCharset()
# }
