When "utf8mb4" is available, use it as the default client charset when invoking standalone "mysql" commands Authored by epriestley on Aug 27 2019, 10:33 PM. Tags None Subscribers None
Details Fixes T13390. We have some old code which doesn't dynamically select between "utf8mb4" and "utf8". This can lead to dumping utf8mb4 data over a utf8 connection in bin/storage dump, which possibly corrupts some emoji/whales. Instead, prefer "utf8mb4" if it's available. Ran bin/storage dump and bin/storage shell, saw sub-commands select utf8mb4 as the client charset.
