    Does sed count 馑 as one character or 3? That is, does echo 馑 | sed s/...// print anything? Commented Apr 17, 2015 at 11:22
  • @immibis Since sed has the g modifier it replaces all occurence also when they follow each other. Also sed should count it as one character, see: echo -ne "馑" | wc -m gives 1. If you count the bytes (wc -c) it would return 3. Did I understand your question correctly? Commented Apr 17, 2015 at 11:28
  • I meant: does . mean "one character" or "one byte"? Commented Apr 17, 2015 at 11:30
  • @immibis I matches one character hence echo 馑 | sed s/...// gives me 馑 (nothing is replaced) Commented Apr 17, 2015 at 11:33

    @chaos: It works under en_US.UTF-8, but doesn't under C. Commented Apr 17, 2015 at 12:28
