First and third part we know each other what is about. You described at
When I wrote:

I intended to highlight that the intent of this "b" flag is often lost in
programs from *nix heritage. And this is a problem.
Granted, if the source never left the *nix world there is no actual problem.
But it is when you try to port it outside that problems surge. Particularly
when the same file is written "w" and read "rb", by the same set of programs
(yes, it happens).
Windows is probably a necessary evil, but this is not an excuse to take the
short track and do the things in a way that only raise problems to the
Of course, this is not against you, there is nothing personnal here.

What do you mean (simple curiosity, I did not get your point)?
Yes Windows does extravagant contortions about codepages with filenames (and
this is disappearing, fortunately), but that should be irrelevant. Yes, C
programs on Windows "eat" CR.
But I fail to see sigificant examples beyond those (I consider the "feature"
of BOM at the beginning of Notepad/RichEdit/whatever UTF-8 files to be an
outright bugbug that had been missed in due time and is now entrenched).

Sorry: you mean, a Unicode application is able to "absorb" any stream
(including erroneous encodings) when programmed in UTF-8 while unable when
programmed in UTF-16?
I would have expected just the reverse (because of the requirements for the
illegality of the overlong encodings).
