I use `sponge` and `ts` (mentioned in the article) pretty regularly, and am really happy for them. I have used `isutf8` a fair amount in the past, but I find it mostly redundant these days (thankfully!) The other one that I don't use very often, but is absolutely invaluable when I do need it, is `ifne` - "Run command if the standard input is not empty". It's like `-r` from GNU `xargs`, but for any command in a pipeline.
