@defopt selection-coding-system
This variable provides a coding system (@pxref{Coding Systems}) which
is used to encode selection data, and takes effect on MS-DOS,
MS-Windows and X@.
is used to encode selection data, and takes effect on MS-Windows and
X@. It is also used in the MS-DOS port when it runs on MS-Windows and
can access the Windows clipboard text.
Under MS-DOS and MS-Windows, it is the coding system by which all
non-ASCII clipboard text will be encoded and decoded; if set under X,
it provides the coding system calls to @code{gui-get-selection} will
decode selection data for a subset of text data types by, and also
forces replies to selection requests for the polymorphic @code{TEXT}
data type to be encoded by the @code{compound-text-with-extensions}
coding system rather than Unicode.
On X, the value of this variable provides the coding system which
@code{gui-get-selection} will use to decode selection data for a
subset of text data types, and also forces replies to selection
requests for the polymorphic @code{TEXT} data type to be encoded by
the @code{compound-text-with-extensions} coding system rather than
Unicode.
Its default value is the system code page under MS-Windows 95, 98 or
Me, @code{utf-16le-dos} under NT/W2K/XP, @code{iso-latin-1-dos} on
MS-DOS, and @code{nil} elsewhere.
On MS-Windows, this variable is generally ignored, as the MS-Windows
clipboard provides the information about decoding as part of the
clipboard data, and uses either UTF-16 or locale-specific encoding
automatically as appropriate. We recommend to set the value of this
variable only on the older Windows 9X, as it is otherwise used only in
the very rare cases when the information provided by the clipboard
data is unusable for some reason.
The default value of this variable is the system code page under
MS-Windows 95, 98 or Me, @code{utf-16le-dos} on Windows
NT/W2K/XP/Vista/7/8/10/11, @code{iso-latin-1-dos} on MS-DOS, and
@code{nil} elsewhere.
