私はPostGres 9.5でRails 4.2.7を使用しています。私のモデルが有効かどうかをチェックすると、私は奇妙なエラーが発生しています。私のような私のPostgresのDBに定義された名前のフィールドを、...持って"valid？"チェック時に "処理中にエラーが発生しました：（ArgumentError）UTF-8の無効なバイトシーケンス"メソッド
しかしname | character varying |
、私は私のモデルにこの値を保存するときに（いくつかのものはカットし、私の編集者から権利貼り付けるないかもしれません...）

そして私は、次の検証ルールをモデルに
if !insert.valid?
を実行
class MyObjectTime < ActiveRecord::Base
belongs_to :my_object
has_one :linked_my_object, class_name: 'MyObject'
belongs_to :state
belongs_to :country
validates :time_in_ms, numericality: { greater_than: 0 }
validates :age, numericality: { greater_than: 0 }, :allow_blank => validates :name, presence: true, unless: :first_name_last_name_empty_and_user_id_is_not?
attr_accessor :name_city, :time_str, :hometown, :division, :age_group_rank_str, :gender_rank_str, :overall_rank_str
私は、文字列の内容を変更せずに、このエラーを回避するにはどうすればよい

...以下のエラーを取得しますか？ PostGresがこのデータを保存することができれば、それが私が気にしている唯一のことです。私はそれに書き込むときに、どのようなエンコーディングのタイプが "name"の値になるかを事前に知っていません。必要に応じて、PostGres列のデータ型を変更できます。
