While I was doing some testing locally, I tried using the translated unit for tablet (錠) and then the Medications page became unusable after saving.

Looking in the logs revealed this:

20:15:42 web.1    |   Medication Load (0.5ms)  SELECT  "medications".* FROM "medications" WHERE "medications"."user_id" = $1 ORDER BY created_at DESC LIMIT $2 OFFSET $3  [["user_id", 1], ["LIMIT", 6], ["OFFSET", 0]]

@nshki @julianguyen before I merge, should I be concerned about this?

This appears to not just be limited to Japanese. I tried this out with German and got the same behavior. I'll log a bug regarding this.
