Signature

locale-file-encoding pathname ef-spec buffer length => new-ef-spec

Arguments

`pathname`⇩	Pathname identifying location of `buffer`.
`ef-spec`⇩	An external format spec.
`buffer`⇩	A buffer whose contents are examined.
`length`⇩	Length (an integer) up to which `buffer` should be examined.

Description

The function locale-file-encoding consults the ANSI code page on Microsoft Windows. If the code page identifier is in win32:*latin-1-code-pages*, locale-file-encoding merges ef-spec with :latin-1. This external format writes Latin-1 on output, giving an error for any non-Latin-1 characters that are written. If the code page identifier is not in win32:*latin-1-code-pages* then locale-file-encoding merges ef-spec with an encoding corresponding to the current code page that gives an error for characters that cannot be encoded.

locale-file-encoding merges ef-spec with :latin-1 on Unix-like systems.

pathname, buffer and length are ignored.
