The term "reference glyph" is somewhat misleading, and may lead some
people to mistakenly believe that the glyphs in the Unicode code
charts are normative references. In fact the Unicode Standard section
16.1 uses the term "representative glyph":

Each character in these code charts is shown with a representative
glyph. A representative glyph is not a prescriptive form of the
character, but one that enables recognition of the intended character
to a knowledgeable user and facilitates lookup of the character in the
code charts. In many cases, there are more or less well-established
alternative glyphic representations for the same character.
