Unicode中，至少有3个冒号。其中一个叫蒙古冒号，看起来我们在蒙古文（和满文）中应该使用蒙古冒号。

(:) Colon （冒号），U+003A：这是使用最广泛的冒号。在东亚，又叫做半角/半形冒号（Halfwidth Colon）。

(：) Fullwidth Colon （全角/全形冒号），U+FF1A：用于中文和日文。

(:) Mongolian Colon （蒙古冒号），U+1804：用于蒙古文、满文等文字的冒号。

这3个冒号横排和竖排情况见下表：

半角冒号和蒙古冒号有区别吗？没有区别！那这样的话，Unicode还需要蒙古冒号吗？我们还要使用蒙古冒号吗？

Is Mongolian Colon Necessary?

In Unicode, at least we can find three colons and one of them is named Mongolian colon. We should use Mongolian colon in Mongolian without hesitation. But is it correct?

(:) Colon, U+003A: This is the most widely used colon. It is also called halfwidth colon in East Asia.

(：) Fullwidth Colon, U+FF1A: This one is mainly used in Chinese and Japanese.

(:) Mongolian Colon, U+1804: This one is designed for Mongolian Script (Mongolian, Manchu and Sibe).
