My point is that the kernel's console is rock solid and dependable.
That is a bold statement.
I've been using the console for around 28 years, now. I don't recall it
crashing at all. My current font and keyboard files are in exactly the
same form as they were 28 years ago. These formats are stable and
dependable.
I've spend the last years working on related code (fbcon) and it
mostly feels dated and unmaintained. Our prime implementation (again
fbcon) has been de-facto unmaintained for years. We recently had
contributors who are pushing the ioctls semantics and found bugs in
fbcon for a number of corner cases.
Something like:

fbdev: Fix out-of-bounds access when rotating console after font resize
Things like kmscon are subject to the vagaries of fashion.
As is clear, I think the console's limitations should be eliminated.
And the rest of us feel the kernel console's code should be eliminated
entirely, when ever possible :)
The rest of you don't appear to be console users. It's easy to advocate
for removal when you don't use it yourself.
FTR I'm not at all interested in eliminating the kernel's console.
Other people, in particular Greg KH, have said this is the current aim.
I'm worried for myself. It is far from clear that there is a suitable
replacement for the kernel's console, and its elimination could easily
happen without that replacement. I suppose I could always (laboriously)
maintain the console for myself personally. Or there's always the BSDs.
I just don't know what I'd do.
Alan, I really appreciate your efforts to enhance the kernel console code!
And I'm not interested to eliminate the kernel console either.
No. IMHO Unicode support would be great.But there are must-have features and nice-to-have features. IMHO for
the kernel console i18n really belongs in the later category.
It's 2026, four decades after VGA was the latest thing, and Unicode
support is merely a nice-to-have?
Thanks!
