Are the glyphs in the Unicode Standard normative?
No. See for example row 9 of the accompanying table (below) showing two glyphs for “numero”. Sometimes, the shape depends on the posture of the font. For example, the letters “a” and “g” as shown in rows 11 and 12 12 of the table. Common variations may be seen in italic and sans-serif fonts. The “y with hook” letter U+01B3, U+01B4 has two common variations as shown in row 13 of the table. Some fonts show the curl on one side for capitals and the other for small letters; some fonts have the curls on the same side.
