Ruby to_yaml utf8字符串 [英] Ruby to_yaml utf8 string

问题描述

如何使ruby to_yaml方法存储带有原始符号但不转义序列的utf8字符串?

How can I make ruby to_yaml method to store utf8 strings with original signs but not escape sequence?

推荐答案

这可能是一个非常糟糕的主意，因为我敢肯定YAML有其编码字符的原因，但似乎并不难撤消:

This is probably a really bad idea as I'm sure YAML has its reasons for encoding the characters as it does, but it doesn't seem too hard to undo:

require 'yaml'
require 'yaml/encoding'

text = "Ça va bien?"

puts text.to_yaml(:Encoding => :Utf8) # => --- "\xC3\x87a va bien?"
puts YAML.unescape(YAML.dump(text)) # => --- "Ça va bien?"
