Thank you for the report. Immediate processing of what is available, combined
with line-buffered output for interactive stdout, has now been implemented,
and will be present in libiconv 1.14.

If you want to have unbuffered output, use 'iconv' like this:
  $ stdbuf -o0 iconv
For example:
  $ (echo -n abc; sleep 1; echo def) | stdbuf -o0 iconv

In passing, your suggestion also gave rise to documentation improvements
about stdbuf [1] and to forthcoming documentation improvements in gnulib [2].
