                  <p>I think I was a little over zealous earlier in
                    stating that Unicode uses &quot;character repertoire&quot; as
                    I described.  I looked again and don&#39;t find that
                    term formally defined in the standard.  However,
                    &quot;repertoire&quot; is used throughout the standard in ways
                    that I believe are consistent with my description. 
                    I wasn&#39;t able to find an alternative formal term.</p>

                  <p>The way I&#39;ve been thinking about it is that a
                    &quot;character repertoire&quot; describes a set of <i>abstract
                      characters</i> (a formal Unicode term) and a
                    &quot;character set&quot; describes a set of <i>encoded
                      characters</i> (a formal Unicode term) that
                    associate each <i>abstract character</i> member of
                    a &quot;character repertoire&quot; with a <i>code point</i>
                    (a formal Unicode term) within a <i>codespace</i>
                    (A formal Unicode term).  See sections 2.4 and 3.4
                    of Unicode 12 and uses of the word &quot;repertoire&quot;
                    within those chapters.  The Unicode standard does

              <div>I think I follow, except that I don&#39;t see whether

                and &quot;abstract characters&quot;.  Is there?  I&#39;m asking
                because if there is not, I&#39;d prefer to standardize the
                formally described term, which sounds like is &quot;abstract
