Today I am face a problem: how to convert 汉字 to \uxxx\uxxx ?
after googled and quickly browsed several posts, I found this answer:
Using active support:
>> require 'rubygems' >> require 'active_support' >> a ='汉字' >> a.encoding => # >> result = ActiveSupport::JSON.encode(a) => "\"\\u6c49\\u5b57\"" >> result.encoding => #
It's strange that both of them are encoded in UTF-8. ( I am confused by this UTF8, UTF16, unicode stuffs... @.@ ) 有点蒙。。。回头把它给补上。
