Ruby 1.9 - 多字节字符无效（utf-8） [英] Ruby 1.9 - Invalid multibyte character (utf-8)

问题描述

我有一个只有这两行的ruby文件：

I have a ruby file with only these two lines:

# encoding: utf-8
puts "—"

当我使用 ruby​​ test_enc.rb 它失败：

test_enc.rb:2: invalid multibyte char (UTF-8)
test_enc.rb:2: unterminated string meets end of file

我不知道如何正确指定字符代码 - （emdash），但vim告诉我它是 151，Hex 97，八进制227 。它与其他字符，如ã也一样失败，所以我怀疑它与那个字符有关。
我在Windows XP上运行，我使用的ruby版本是：

I don't know how to properly specify the character code of — (emdash), but vim tells me it is 151, Hex 97, Octal 227. It fails the same way with other characters like ã as well, so I doubt it is related specifically to that character. I am running on Windows XP and the version of ruby I'm using is:

ruby 1.9.1p430 (2010-08-16 revision 28998) [i386-mingw32]

我觉得有一些很明显我在这里失踪。任何想法？

I feel like there is something very obvious I am missing here. Any ideas?

编辑：今天学习了一个有关假设的有价值的教训 - 特别是假设您的编辑器使用UTF-8而没有实际检查。糟糕！

Learned a valuable lesson about assumptions today - specifically assuming your editor IS using UTF-8 without actually checking it. Oops!

感谢您快速准确地回覆所有邮件！

Thanks for the quick and accurate replies all!

重新编辑'为utf-8正确设置vim'变得太大了，并且与这个问题没有真正的关系，所以现在是一个单独的问题。

EDIT AGAIN: The 'setting up vim properly for utf-8' grew too big and wasn't really relevant to this question, so it is now a separate question.

推荐答案

鉴于Ruby明确地呼吁你注意UTF-8，我强烈怀疑你没有实际写出一个UTF-8文件开始。确保Vim（或用于创建文件的任何文本编辑器）真的设置为写UTF-8。

Given that Ruby is explicitly calling your attention to UTF-8, I strongly suspect that you haven't actually written out a UTF-8 file to start with. Make sure that Vim (or whatever text editor you're using to create the file) is really set to write out UTF-8.

请注意，在UTF-8中，任何非ASCII字符将由多个字节表示，而不是如Vim诊断中所述的单个字节。我建议使用二进制文件编辑器（或转储，或任何）来真正显示文本文件中的内容。有些东西还没有编码的一些先入为主的概念，甚至连一个文本文件都没有。

Note that in UTF-8, any non-ASCII character will be represented by multiple bytes, not a single byte as you've described from the Vim diagnostics. I'd recommend using a binary file editor (or dump, or whatever) to really show what's in the text file though. Something that doesn't already have some preconceived notion of the encoding - something that isn't even trying to think of it as a text file.

记事本让你写出来一个UTF-8文件，所以你可能想试试看看会发生什么。 （我没有自己安装Ruby，否则我会为你试试。）

Notepad lets you write out a file in UTF-8, so you might want to try that just to see what happens. (I don't have Ruby installed myself, otherwise I'd try it for you.)
