[TCLCORE] TIP 716 ready for comments

[<apn...@ya...>]

 <https://core.tcl-lang.org/tips/doc/trunk/tip/716.md> TIP 716: New command
"encoding user", remove UTF-8 manifest setting on Windows is ready for
comments. It proposes reversion of a change made in 9.0 to tclsh and wish
Windows manifests while keeping compatibility with 9.0.{0,1}.

 

Apologies for my usual verbosity, but when I brought this up in the mailing
list prior to the previous release, the comments wandered into why UTF-8
should be the default. I've tried to better explain that is not the issue.

 

I will point out that the original change to the manifest, which made UTF-8
the default on Win 10 1903+ and Win 11, should have been TIP'ed as it
overrides user settings and is a change in behavior of a public API and
command. It's water under the bridge now that 9.0 has shipped so the TIP
maintains status quo and only changes the implementation. It also adds a new
encoding user command and an -encoding option to exec as a workaround for
compatibility issues introduced by forcing a UTF-8 default.

 

Note the implementation in the tip-716 branch is mostly complete but not
ready for review. I am only looking for comments on the proposal before
proceeding further with tests and docs.
