Issue with Currency format D3

I’m trying to set up the currency format in superset charts but it is always displayed in the American format. ($ 1,234.56)

Tried the solution present in #3972 by @PeterCahn by changing the superset/assets/node_modules/d3-format/src/defaultLocale.js file to the desired one and didn’t work for the currency problem.

  decimal: ",",
  thousands: ".",
  grouping: [3],
  currency: ["R$", ""],
  dateTime: "%d/%m/%Y %H:%M:%S",
  date: "%d/%m/%Y",
  time: "%H:%M:%S",
  periods: ["AM", "PM"],
  days: ["Domingo", "Segunda", "Terça", "Quarta", "Quinta", "Sexta", "Sábado"],
  shortDays: ["Dom", "Seg", "Ter", "Qua", "Qui", "Sex", "Sáb"],
  months: ["Janeiro", "Fevereiro", "Março", "Abril", "Maio", "Junho", "Julho", "Agosto", "Setembro", "Outubro", "Novembro", "Dezembro"],
  shortMonths: ["Jan", "Fev", "Mar", "Abr", "Mai", "Jun", "Jul", "Ago", "Set", "Out", "Nov", "Dez"]});

Expected results

Expected to see the currency as R$ 1.234,56

Actual results

$ 1,234.56

Screenshots

I highlighted the date because looks like the defaultLocale is working for date/time.

We are having the same issue - getting this https://github.com/apache/incubator-superset/issues/3972#issuecomment-535037981 working in some way would be a dynamite upgrade for deploying across non-US countries.
