Ruby正则表达式错误：不兼容的编码regexp匹配（ASCII-8BIT regexp与UTF-8字符串） [英] Ruby Regex Error: incompatible encoding regexp match (ASCII-8BIT regexp with UTF-8 string)

问题描述

我收到两个错误，都围绕编码和两个相关。

I'm getting two errors, both revolving around encoding and both related.

启动WEBrick时遇到的第一个错误（技术上， / p>

The first error (technically, a warning) I get when starting up WEBrick:

/Users/USERNAME/example/config/initializers/bb-ruby.rb:54: warning: invalid Unicode Property \P: /\:\-?\P/

它所引用的行是： / \：\-？\ P /，

这只是一个正则表达式，此块：

It's just a bit of regex, ultimately part of this block:

@@tags['Razzing'] = [
  /\:\-?\P/,
  '<img src="/assets/emoticons/razzing.png">',
  'Razzing',
  ':P',
  :razzing]

$ b ）...

Then, I also get the following error when parsing some strings (presumably due to this same line)...

Encoding::CompatibilityError
incompatible encoding regexp match (ASCII-8BIT regexp with UTF-8 string)

我运行Ruby 1.9.2和Rails 3.2.1。

I'm running Ruby 1.9.2 and Rails 3.2.1.

推荐答案

您的正则表达式被编译为ASCII-8BIT。

Your Regex is being "compiled" as ASCII-8BIT.

声明文件顶部的正则表达式声明：

Just add the encoding declaration at the top of the file where the Regex is declared:

# encoding: utf-8

完成了。现在，当Ruby解析你的代码时，它将假设你使用的每个文本（Regex，String等）以UTF-8编码指定。

And you're done. Now, when Ruby is parsing your code, it will assume every literal you use (Regex, String, etc) is specified in UTF-8 encoding.

UPDATE ： UTF-8 现在是Ruby 2.0及更高版本的默认编码。

UPDATE: UTF-8 is now the default encoding for Ruby 2.0 and beyond.
