In any case, this is not relevant to the question at hand, which aims to completely side-step find-file when `load'ing a (utf-8) .el file. As for the .el8 proposal: seriously, the problem I'd like to address is (as others have said several times already) a very minor one, so the solution has to be *really* lightweight to be worth the trouble. Switching to .el8 would bring a whole lot of trouble for *very* little benefit. E.g. writing the C code that checks for the presence of a `coding' tag is already more trouble than I'm willing to go through to fix this issue. OTOH, the "new utf-8 marker" I'd like to come up with should ideally also work as a "lexical-binding" marker. IOW it would serve as a kind of "new Elisp" marker. So maybe a unicode BOM marker would be too discrete and we could go for something more clearly visible instead. Stefan
