不兼容的字符编码:ASCII-8BIT和UTF-8

Mic*_*per 69 ruby haml ruby-on-rails ruby-on-rails-3

我使用Ruby 1.9.2和Rails 3.0.5

我有以下错误:

不兼容的字符编码:ASCII-8BIT和UTF-8

它与我认为的数据库无关.

错误是在视图中惹恼这一行(只是一个div haml调用):

我通过以下步骤解决了它:

  • 确保config.encoding = "utf-8"在application.rb文件中.
  • 确保您使用的是'mysql2'宝石.
  • 放在# encoding: utf-8包含UTF-8字符的文件顶部.

  • <App Name>::Application.initialize!在environment.rb文件的行上方,添加以下两行:

    Encoding.default_external = Encoding::UTF_8
Encoding.default_internal = Encoding::UTF_8

  • 使用`mysql2`对我来说很好,谢谢! - 将`database.yml`中的适配器更改为`mysql2`吧! (16认同)
  • 我不得不使用gem'mysql2','<0.3',如下所示:http://stackoverflow.com/questions/5840742/version-of-mysql2-0-3-2-doesnt-ship-with-the-activerecord -adapter捆扎任何 (2认同)

尝试找到导致此问题的确切行,然后强制执行UTF8编码,此解决方案对我有用.

title.to_s.force_encoding( "UTF-8")

  • 甚至在标准的ruby中也似乎有一些功能似乎导致了这一点.对我来说,它是Digest :: MD5.digest(Random.rand(10000).to_s) (8认同)

我怀疑你是否将Haml模板的一部分复制/粘贴到文件中,或者你正在使用非Unicode /非UTF-8友好编辑器.

看看您是否可以在UTF-8友好编辑器中从头开始重新创建该文件.任何平台都有很多,看看这是否能解决您的问题.首先擦除线#content并手动重新输入.

the*_*Man 11

ASCII-8BIT是Ruby对普通0-0x7f ASCII字符集之上字符的描述,它是单字节字符.通常情况下,这将是ISO-8859-1,或其兄弟之一.

如果您可以识别导致问题的字符,那么您可以告诉Ruby 1.9.2将该字符的字符集转换为UTF-8.

詹姆斯格雷写了一系列博客,谈论这些问题以及如何处理它们.我建议你去看看.

不兼容的字符编码:ASCII-8BIT和UTF-8

这通常是因为您尝试连接两个字符串,而另一个包含不映射到另一个字符串的字符集的字符.ISO-8859-1中的字符在UTF-8中没有等效字符,反之亦然,如何处理字符串连接与这些不兼容性需要程序员介入.

  • Ruby对ISO-8859-1的描述是"ISO-8859-1"."ASCII-8BIT"是ruby对二进制数据的描述. (2认同)

你可以强制UTF8 force_encoding(Encoding::UTF_8):

我安装了gem包mysql2.
