Has this query some consequences on already present records?

AFAIK, there should be no problem because all characters from latin1_swedish_ci are present in utf8mb4_unicode_ci. There might be problems with conversion if there were charset columns defined as foreign keys, but this is not the case.
I tried this query on our development instance (iam-dev) having that table already populated, and it succeeded.
URLs added in the PR description! :) |
