为什么我不能在ruby中分配哈希数组？

Question

我在ruby中定义哈希数组时遇到问题。我找到了一些解决方案，但没有人回答这个小代码示例的错误：

users = [{:id => "1", :imie => "Szymon", :punkty => "0"}, 
{:id => "2", :imie => "Krzysiek", :punkty => "0"}, 
{:id => "3", :imie => "Przemek", :punkty => "0"}, 
{:id => "4", :imie => "Paweł", :punkty => "0"}]

谢谢！

Answer 1

此条目的问题 - :imie => "Paweł"。 无效的多字节字符（US-ASCII）

像这样使用：

# encoding: UTF-8
users = [{:id => "1", :imie => "Szymon", :punkty => "0"}, 
{:id => "2", :imie => "Krzysiek", :punkty => "0"}, 
{:id => "3", :imie => "Przemek", :punkty => "0"}, 
{:id => "4", :imie => "Paweł", :punkty => "0"}]

p users.class #=>Array

使用以下内容：

Encoding.default_external = 'utf-8'
Encoding.default_internal = 'utf-8'
