  iconv stdio buffering

Bug description:
  Tool "iconv" suffers from the stdio buffering problem described here:

  https://stackoverflow.com/questions/14472179/how-do-i-perform-a-
  streaming-character-conversion

  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."

  Solutions are described in this page:

  http://www.pixelbeat.org/programming/stdio_buffering/

  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)."

  [known workaround]
  Use `recode` instead.
