这样设计的原因和域名有点相似，RFC883中有部分定义，不区分大小写，不过域名中支持6789数字，这里这样设计主要还是出于编码的考虑：
Loss of case sensitive data must be minimized. Thus while data for x.y and X.Y may both be stored under x.y, data for a.x and B.X can be stored as a.x and B.x, but not A.x, A.X, b.x, or b.X. In general, this prevents the first component of a domain name from loss of case information.
