They are both IDs. One is from the range of numbers from 0 to 1114111
(10FFFF base 16), the other is from the range of strings of characters
each in the range {U+0020, U+002D, U+0030-U+0039, U+0041-U+0056} with
rules for equality matching that lets us compare with mixed-case forms.

In both cases we have a value which can be compared for equality with
another value, which refers to at most one entity, and which offers a
reasonable guarantee of immutability (due to the stability on names that
started this thread). They're both IDs.

On the other hand, the name is not always very good as a human readable
description. It's unpleasant in this context at the best of times (UPPER
CASE TENDS TO TIRE THE EYES VERY QUICKLY), it's often considered
incorrect, and it very often when accurate is still incomplete as to the
different uses made of the character in different contexts, all of which
makes it occasionally poor as a human readable description (pretty much
every time people have wanted to have a name changed, at least one
person thought it failed in this regard).

The human-readability is a convenience for those using the identifiers,
but it's more akin to the human-readability of programming and markup
languages than the human-readability of a well-written reference book.
