Comment:

 This is a duplicate of #14456, you're hitting an issue where Microsoft has
 started shipping `icuuc` in Windows. GHCi is picking up this version but
 the version doesn't seem usable due to different symbol names.

 It's been fixed in 8.4. using `lib` is explicitly forcing it to pick the
 `import library, libicuio.dll.a` which directs it to the right dll.

 Under normal circumstances, those (libicuio vs icuio) two are *roughly*
 equivalent. There are some diffences but it should all work out to the
 same if you have your environment correct.

 I'm closing it as a duplicate. I'm not sure the release manager would
 agree that this should be backported into the up and coming ghc 8.4.3 bug-
 fix release for ubuntu.
