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

问题描述

如何制作 ruby​​ to_yaml 方法来存储带有原始符号但不包含转义序列的 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，因为我确信 YAML 有它的原因来编码字符，但它似乎并不难撤消:

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) # => --- "xC3x87a va bien?"
puts YAML.unescape(YAML.dump(text)) # => --- "Ça va bien?"
