Each character in the Unicode Standard is designated by one unique hexadecimal number. To mark a hexadecimal number as a ‘Unicode hexadecimal scalar value’, to give it its formal name, we prefix the hex number by ‘U+’. So the character ‘Latin small letter a’ is U+0061. Unicode hexadecimal scalar values are at least four digits long, and five-digit ones are also used regularly in Brill publications: for instance, U+10000 designates LINEAR B SYLLABLE B008 A: 𐀀 (
