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 Unicode character a (‘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+1D510 designates 𝔐 (‘MATHEMATICAL FRAKTUR CAPITAL M’), a symbol often used to indicate the Masoretic text of the Hebrew bible. U+20000 is 𠀀, a Chinese character (Mandarin pronunciation ‘hē’).
