In every XML tag name, the function replaces any underscore character (_) with a dash character (-).

对于每个xml标记名，该函数将其中的下划线(_)该为连字符(-)。

Because the replacement text for - is a character reference, it's exactly the same as typing an en dash character.

由于—的替代文本是一个字符引用，因此它等同于输入一个短横线字符。

如果某部分中有一个破折号或者一个特殊的字符，那这个词就有可能太长。
