Re: Q: something like autoload for coding-systems?

[Richard Stallman]

    By the way, for that, we must pay attention to
    find-coding-systems-region.  Without loading a coding
    system, it can't find out that coding system is safe or not.
    Is it ok that find-coding-systems-region won't return such
    coding systems that are not yet loaded?

Is it possible to identify just a part of the coding system info
which is sufficient for find-coding-systems-region, have that part
always loaded, and autoload the rest?

    It might be (almost) okay; it's certainly no worse than what we have
    now ;-)

It could indeed be worse.  If this information currently is always
loaded, then currently find-coding-systems-region always can handle
all coding systems.  Making it fail to handle some coding systems
COULD make it worse.

    It could be argued that find-coding-systems-region is mostly called
    when we output text.  If that's so, in many cases the appropriate
    coding tables would be already loaded, when that text was decoded
    during input.

This might be a valid argument.
