As Peter correctly noted, nothing will move if everyone is driven by this
logic. The change must be done by incremental steps, especially since I do
not see Microsoft changing their implementation unilaterally (vendor
lock-in?). People in WG21 can try to push it into the standard in some form
(e.g. mandate or at least recommend the basic execution character set to be
capable of storing Unicode). This would be great, but I estimate it to be a
path of greater resistance.

Depends on what part of the library. Most of the standard library string
handling functions are encoding agnostic.

It replaces all those standard functions that interact with with the
system. Which other do matter? Those that specifically deal with encodings
(mbtowc, etc..) are useless on Windows because they do not support UTF-8...

Agree, and see above.
