Basically, when piping to iconv in an interactive session, output stutters. Tool "stdbuf" does not help. From the page above: "But it looks like iconv is managing the buffering internally itself - it's nothing to do with the Linux pipe buffer."
iconv should have a command-line switch to help. From the page above:
"Note tail's stdout buffer would also have this problem, but tail -f calls fflush
on the stdout stream when new data is received to alleviate this
(as do tcpdump -l, grep --line-buffered and sed --unbuffered for example)."
Tool "iconv" suffers from the stdio buffering problem described here:
