Ruby on rails Rails-RSPEC不完整的多字节字符错误

我在ruby 1.9.3中使用Rails 3.2.13。我不断得到以下错误：

Failure/Error: @user = Fabricate :user, role_ids: [role.id]
PG::Error:
   incomplete multibyte character

     Failure/Error: get :show, { id: @project.id }
     ActiveRecord::StatementInvalid:

在上面第6行调用的制造商如下所示：

require 'spec_helper'

describe Api::V1::ProjectsController do
  before do
    role = Fabricate :data_collector_role
    @user = Fabricate :user, role_ids: [role.id] # this is line 6
    @project = Fabricate.build(:project, proposal: Fabricate(:full_proposal))
    @project.save(validate: false)
    @permission = Fabricate :permission, user: @user, project: @project
    @project2 = Fabricate.build(:project, proposal: Fabricate(:full_proposal))
    @project2.save(validate: false)
    request.env["HTTP_ACCEPT"] = 'application/json'
    request.env['HTTP_AUTHORIZATION'] =   ActionController::HttpAuthentication::Token.encode_credentials(@user.api_key)
  end

Fabricator :user do
    username { sequence(:username) { |n| "foo#{n}" } }
    password 'foobar'
    password_confirmation 'foobar'
    email_address "user@example.com"
    home_phone "123456789"
    work_phone "456789189"
    sales_channel
end

同样的代码在其他规范中被调用，而这些规范不适用于API控制器，并且它们在100%的时间内工作

RSPEC偶尔会完全崩溃，并出现以下错误：

将其添加到文件spec/controllers/api\u controllers/projects\u controller\u spec.rb的顶部

# !/usr/bin/env ruby
# encoding: utf-8

检查这是否有助于@PriteshJ测试中没有可能导致问题的非UTF-8字符。感谢您指出这一点，但很遗憾，这无助于更新答案，请再试一次。不幸的是，我将上面的行添加到项目中的每个.rb文件中，错误仍然存在。我认为情况也不是这样。链接中的脚本没有找到任何文件。我还对我所有的.rb文件运行了“file--mime”，它们以ASCII或UTF-8的形式返回，这应该没问题，因为ASCII是UTF-8的一个子集。
