changed migration which will change db/table/col to utf8 encoding (#1810

)

* changed migration which will change db/table/col to utf8 encoding

Was originally going to the best practice standard of utf8mb4 but scaled
back my ambition when we encounted column size too large. While we do want
CJK characters (maybe even emojis) this won't break anything that isn't
already broken.
