修复破解的UTF8编码(Fixing Broken UTF8 encoding)

 下划线和光标代表Listbox项目的不同属性 - 
 
 
 
 下划线标记（它是Listbox的默认活动activestyle属性）显示活动项目。 
 
 
 光标用于（a）选定的项目。 
 
 
 默认情况下，Tab键在此上下文中交替显示“活动”状态，因此它不会影响游标。 
 
 要更改光标位置，我们需要将活动项目设置为（a）所选项目。 我通过将Tab键绑定到执行此额外manouver的lambda函数来完成此操作： 
 
l1.bind('<Tab>', lambda e: l2.select_set(l2.index(ACTIVE)))
l2.bind('<Tab>', lambda e: l1.select_set(l1.index(ACTIVE)))
 
 活动索引作为参数提供给相应的select_set() ，然后将光标移动到下划线项目上。 
 
 注：我认为对于更一般的情况，事件e应该用于拾取活动项目，而不是直接引用列表框。 但是，这似乎适用于2个列表框。 

The underscore and cursor represent different attributes of Listbox items - 
 
 
 
The underscore marking, which is the default activestyle attribute of a Listbox, shows the active item. 
 
 
The cursor is for (a) selected item(s).
 
 
The Tab key, by default, alternates the "active" state in this context, so it does not affect the cursor. 
 
To change the cursor position, we need to set the active item to be the (a) selected item as well. I've done so by binding the Tab key to lambda functions that perform this additional manouver:
 
l1.bind('<Tab>', lambda e: l2.select_set(l2.index(ACTIVE)))
l2.bind('<Tab>', lambda e: l1.select_set(l1.index(ACTIVE)))
 
The active index is given as an argument to the appropriate select_set(), which then moves the cursor over the underscored item.
 
Note: I think that for a more general case, the event e should be used to pick up the active item, rather than referring to the Listboxes directly. However, this seems to work fine for 2 listboxes.
