FasterCSV和非拉丁字符

Question

Iv最近编写的代码将帮助我使用FasterCSV和rails将SQL数据库导出到CSV中。然而，我的数据库中有些部分包含繁体中文字符。当我输出它的时候，我得到了？作为CSV文件中的输出。Iv已经尝试更改$KCODE = 'u‘，以便FasterCSV使用UTF-8对CSV文件进行编码，但没有成功。Iconv来转换编码也给了我奇怪的结果。源代码如下：

def csv
@lists = Project.find(:all, :order=> (params[:sort] + ' ' + params[:direction]), :conditions =>  ["name LIKE ?", "%#{params[:selection]}%"])

csv_string = FasterCSV.generate do |csv|
  csv << [<bold> "Status","Name","Summary","Description","Creator","Comment","Contact Information","Created Date","Updated Date"]

  @lists.each do |project|
    csv << [project.status, project.name, project.summary, project.description, project.creator, project.statusreason, project.contactinfo, project.created_at, project.updated_at]
  end
end

filename = Time.now.strftime("%Y%m%d") + ".csv"
send_data(csv_string,
  :type => 'text/csv; charset=utf-8; header=present',
  :filename => filename)

结束

谢谢,

我不习惯使用中文字符，但您可以尝试在generate调用中将:encoding选项添加到'u‘(UTF-8)：

...
csv_string = FasterCSV.generate(:encoding => 'u') do |csv|
...

顺便说一句，我建议使用named_scopes，而不是这样写：

Project.find(:all, :order=> (params[:sort] + ' ' + params[:direction]), :conditions =>  ["name LIKE ?", "%#{params[:selection]}%"])

祝好运!
