[Touch-packages] [Bug 1568726] Re: iconv stdio buffering
Hi! Thanks for raising the issue. Given the relative complexity of the patch and the low number of affected people, I don't feel we should be shipping this as a Ubuntu- specific patch. It might be a better idea for you to raise the issue on the upstream ML, possibly amending the original patch to take the various review remarks into account? ** Description changed: 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.
