UAX #34 has the following to say about unique naming of character
sequences, and by extension, characters:
> R3: Like character names, names for sequences are unique if they are
> different even when SPACE and medial HYPHEN-MINUS characters are
> ignored, and when the strings “LETTER”, “CHARACTER”, and “DIGIT” are
> ignored in comparison of the names.
>
> The following two character names are exceptions to this rule, because
> they were created before this rule was specified:
>
> 116C HANGUL JUNGSEONG OE
> 1180 HANGUL JUNGSEONG O-E
>
> Examples of unacceptable names that are not unique:
>
> SARATI LETTER AA
> SARATI CHARACTER AA
I'm wondering if this rule applies to the string "LETTER" in the
following character names:
U+210C BLACK-LETTER CAPITAL H
U+2111 BLACK-LETTER CAPITAL I
U+211C BLACK-LETTER CAPITAL R
U+2128 BLACK-LETTER CAPITAL Z
U+212D BLACK-LETTER CAPITAL C
In other words, would a hypothetical character name "BLACK CHARACTER
CAPITAL H" violate this rule?
(This is not meant as a joke, by the way; I'm playing around with
algorithms for efficient storage of character names.)
