It's that unflushed output sitting there when a :encoding is pushed can't then be flushed with $| or ->flush(). > Or add print "" after turning autoflush on. I tried that, it has no effect. Printing a non-empty string does make it go. My gues is that :encoding will pass on a flush call to its sublayer only when it's seen output pass through itself. I guess not flushing the sublayer when you know there's nothing to go out is a nice optimization, but when first pushed it can't know what might or might not be sitting beneath it. (As before, assuming "make the output go" is what flush really means.)Thread Previous
