So would an alternative be to use iconv only on z/OS (and hopefully this is a temporary solution until icu is supported on z/OS) and use icu on all other platforms?

Now that IBM has embraced LLVM and Clang, I would expect it to be possible to build ICU for z/OS again with moderate porting effort. It would be great if someone from IBM could confirm whether such an effort is underway (@hubert.reinterpretcast?).
