Here are the Lisp facilities for working with coding systems:
This function returns a list of all coding system names (symbols). If
base-only is non-nil, the value includes only the base coding
systems. Otherwise, it includes alias and variant coding systems as well.
This function returns t if object is a coding system name or
nil.
This function checks the validity of coding-system. If that is valid,
it returns coding-system. Otherwise it signals an error with
condition coding-system-error.
This function returns the type of end-of-line (a.k.a. eol)
conversion used by coding-system. If coding-system specifies a
certain eol conversion, the return value is an integer 0, 1, or 2, standing
for unix, dos, and mac, respectively. If
coding-system doesn't specify eol conversion explicitly, the return
value is a vector of coding systems, each one with one of the possible eol
conversion types, like this:
(coding-system-eol-type 'latin-1)
⇒ [latin-1-unix latin-1-dos latin-1-mac]
|
If this function returns a vector, Emacs will decide, as part of the text
encoding or decoding process, what eol conversion to use. For decoding, the
end-of-line format of the text is auto-detected, and the eol conversion is
set to match it (e.g., DOS-style CRLF format will imply dos eol
conversion). For encoding, the eol conversion is taken from the appropriate
default coding system (e.g., default-buffer-file-coding-system for
buffer-file-coding-system), or from the default eol conversion
appropriate for the underlying platform.
This function returns a coding system which is like coding-system
except for its eol conversion, which is specified by eol-type.
eol-type should be unix, dos, mac, or
nil. If it is nil, the returned coding system determines the
end-of-line conversion from the data.
eol-type may also be 0, 1 or 2, standing for unix, dos
and mac, respectively.
This function returns a coding system which uses the end-of-line conversion
of eol-coding, and the text conversion of text-coding. If
text-coding is nil, it returns undecided, or one of its
variants according to eol-coding.
This function returns a list of coding systems that could be used to encode a text between from and to. All coding systems in the list can safely encode any multibyte characters in that portion of the text.
If the text contains no multibyte characters, the function returns the list
(undecided).
This function returns a list of coding systems that could be used to encode
the text of string. All coding systems in the list can safely encode
any multibyte characters in string. If the text contains no multibyte
characters, this returns the list (undecided).
This function returns a list of coding systems that could be used to encode all the character sets in the list charsets.
This function chooses a plausible coding system for decoding the text from start to end. This text should be a byte sequence (voir la section Explicit Encoding and Decoding).
Normally this function returns a list of coding systems that could handle
decoding the text that was scanned. They are listed in order of decreasing
priority. But if highest is non-nil, then the return value is
just one coding system, the one that is highest in priority.
If the region contains only ASCII characters except for such
ISO-2022 control characters ISO-2022 as ESC, the value is
undecided or (undecided), or a variant specifying end-of-line
conversion, if that can be deduced from the text.
This function is like detect-coding-region except that it operates on
the contents of string instead of bytes in the buffer.
Voir Process Information, in particular
the description of the functions process-coding-system and
set-process-coding-system, for how to examine or set the coding
systems used for I/O to a subprocess.
