How to use Base64.urlsafe_decode64 for a gon variable.

[mgtf]

Hi,

I'm using something like

  protected

  def init_gon
    ...
    gon.vapid_public_key = Base64.urlsafe_decode64(Rails.application.secrets.vapid[:public_key])
  end

But the Gon::Base.render_data complains that : "\xD2" from ASCII-8BIT to UTF-8
I've tried different string conversion using force_encoding method without success.

Any hints ?
Thanks a lot
