Overview

While our database support utf8mb4, the same isn't true for the warehouse and there may be even tighter constraints downstream in NPG. This allows us to constrain affected fields until the downstream processes add support. This validator produces an error message listing the problem characters.

utf8mb3 is the subset of utf8 which can be represented in 3 bytes or fewer and is what is supported when the mysql character-set is set to utf8. Typically if covers the majority of language characters, but excludes emoji

A similar validator should be added for any tighter restrictions that may be applied for other fields.
