奇怪的字符编码 [英] Weird Characters encoding

问题描述

我在我的参数中有一个奇怪的行为，它们以utf-8的形式传递，但特殊字符管理不善。
而不是1个特殊字符，我有2个字符：普通字母+口音。

 参数：{ name="Mylène.png，_cardbiz_session=>be1d5b7a2f27c7c4979ac4c16fe8fc82，authenticity_token=>9vmJ02DjgKYCpoBNUcWwUlpxDXA8ddcoALHXyT6wrnM =，asset=> {file=>＃& ActionDispatch :: Http :: UploadedFile：0x007f94d38d37d0 @ original_filename =Mylène.png，@ content_type =image / png，@ headers =Content-Disposition：form-data; name = \asset [file] \ ; filename = \Myle\xCC\x80ne.png\\r\\\
Content-Type：image / png\r\\\
，@ tempfile =＃<文件：/ var / folders / q5 / yvy_v9bn5wl_s5ccy_35qsmw0000gn / T / RackMultipart20130805-51100-1eh07dp> >}，id="copie-de-sm} 
  

：

• logger.debug file_name


• logger.debug file_name.chars.map（&） to_s）.inspect

每次相同的结果：

• Mylène


• [M，y，l，e，，n，e]

当我尝试使用文件名作为匹配器，已经存在的名称正确编码为utf-8时，您会看到我的问题;）

• 编码是utf-8到处。


• 在ruby 1.9.3和rails 3.2.14下工作。


• 在任何涉及的文件中添加了#encoding：utf-8。

作为一个想法，接受它！

我也在这里发表了一个问题： https://github.com/carrierwaveuploader/carrierwave/issues/1185 ，但不知道它的载波波问题还是我丢失的东西...

解决方案

似乎要链接到MACOSX。

https：//www.ruby- forum.com/topic/4407424 解释它，并提及 https：//bugs.ruby -lang.org/issues/7267 了解更多详细信息和问题。

MACOSX将特殊字符分解为 utf8-mac ，而不是 utf-8 ...

虽然您无法知道文件名的编码，但只是预先确定。

感谢我们的Linux人员在哪里工作正常。 ;）

  file_name.encode！（'utf-8'，'utf-8-mac'）。chars.map &：to_s）
  

I have a weird behaviour in my params whichare passed as utf-8 but the special characters are not well managed. Instead of 1 special character, I have 2 characters: the normal letter + the accent.

Parameters: {"name"=>"Mylène.png", "_cardbiz_session"=>"be1d5b7a2f27c7c4979ac4c16fe8fc82", "authenticity_token"=>"9vmJ02DjgKYCpoBNUcWwUlpxDXA8ddcoALHXyT6wrnM=", "asset"=>{"file"=># < ActionDispatch::Http::UploadedFile:0x007f94d38d37d0 @original_filename="Mylène.png", @content_type="image/png", @headers="Content-Disposition: form-data; name=\"asset[file]\"; filename=\"Myle\xCC\x80ne.png\"\r\nContent-Type: image/png\r\n", @tempfile=# < File:/var/folders/q5/yvy_v9bn5wl_s5ccy_35qsmw0000gn/T/RackMultipart20130805-51100-1eh07dp > >}, "id"=>"copie-de-sm"}

I log this:

• logger.debug file_name
• logger.debug file_name.chars.map(&:to_s).inspect

Each time, same result:

• Mylène
• ["M", "y", "l", "e", "̀", "n", "e"]

As i try to use the filename as a matcher with already existing names properly encoded utf-8, you see my problem ;)

• Encodings are utf-8 everywhere.
• working under ruby 1.9.3 and rails 3.2.14.
• Added #encoding: utf-8 in top of any file involved.

I anyone as an idea, take it !

I also published an Issue here : https://github.com/carrierwaveuploader/carrierwave/issues/1185 but not sure if its a carrierwave issue or me missing something...

解决方案

Seems to be linked to MACOSX.

https://www.ruby-forum.com/topic/4407424 explains it and refers to https://bugs.ruby-lang.org/issues/7267 for more details and discution.

MACOSX decomposing special characters into utf8-mac instead of utf-8...

While you can't know the encoding of a file name, just presupose it.

Thanks to our Linux guy where it works properly. ;)

file_name.encode!('utf-8', 'utf-8-mac').chars.map(&:to_s)
