如何在Rails控制台中输入Unicode字符？ [英] How to input Unicode character in Rails console?

问题描述

在使用Rails控制台时，当我输入ä时，会出现 \U + FFC3\U + FFA4 。
当然我可以在rails之外输入Unicode字符。

While using Rails console, when I input ä, \U+FFC3\U+FFA4 appears. Of course I can input Unicode characters outside of rails.

我正在使用Ruby 2.0.0p247，在Max OS X 10.7.5中使用Rails 4.0.0。
