There seems to be quite large segments of developers working on functionality which "handles text" as immutable whole blobs, in which case one really doesn't have to know anything about unicode.
However, as soon as you want to look into the text contents of the objects of that object store and handle parts of it, even in the very simplest way (e.g. checking whether the stored object contains some character, or whether two text messages stored in that object store are the same) then you can't treat them as bytes anymore, and all the concerns listed in this article suddenly become relevant for your team.
