Sure.  Though, I see this mail in linux-utf8 mailing list.

But, I think it's not that difficult to fix this behaviour
so that it breaks a line at an unencodable word.

If that is possible (i.e. users allows that), yes.   But,
why calling select-safe-coding-system is not good?

Those people should have already encountered a problem as I
wrote before because they can't decode a text back with the
same coding system.

By the way, the function choose_write_coding_system ()
checks a coding system specified in file-coding-system-alist
by select-safe-coding-system.
