The migration page is now extended by the change of the MS-Windows 
system encoding:

https://core.tcl-lang.org/tcl/info/e16612341c1416c5

and the deprecated Tcl_Winxxx functions:

https://core.tcl-lang.org/tcl/info/d6ff4a080d8f9e87

I try to use full examples. The Tcl_Winxxx functions were never fully 
documented. I hope, this works.

About TIP 548:
https://core.tcl-lang.org/tips/doc/trunk/tip/548.md

I am hesitant to document more. Basically, I don't understand the text.
Or it is incomplete. The type "wchar_t" is 16 bit on Windows, but may be 
another size on other platforms. But this is a platform issue, not a TCL 
issue.
I am also not happy by the word "utf-8". Here, not the utf-8 encoding is 
ment, but the TCL variant replacing the 0 Codepoint. Or is this not the 
case, e.g. the functions may not handle 0 bytes.
Also, there is nothing written about eventual surrogates for the 16 bit 
functions.

More questions than answers as usual....

Thanks for all,
Harald

P.S. I have retried my test with the updated branch. This does not make 
any difference (and should IMHO not). The result is ok and now, we have 
migration text ;-).
