Is it necessary to set COLLATE additionally for each field in mysql?

Question

MySQL

I noticed that in Wordpress, in addition to the fact that it costs
DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci, COLLATE=utf8mb4_unicode_ci is
also set for each text field.
Does this mean that if I add this encoding for new tables, I must also specify COLLATE for each field, or is it enough to specify DEFAULT COLLATE?

Answer 1

Base COLLATE is inherited from the server settings, tables - from the base, columns - from the table, so it makes sense to set explicitly only when changing.
