Subject: Re: [PATCH v2] kernel: escape non-ASCII and control characters in
printk()
Go back and read what I said originally, and think about it.
You have to look at the IUTF bit of the relevant console you are logging
to.
As far as I can see we need:
No IUTF: block various control codes + CSI
IUTF: block various control codes only
But arbitarily blocking anything non ASCII is going to make a mess in
anything non American. Even English needs UTF-8.
