| Unicode is a system that assigns numeric values for all the
characters that are coded within Unicode. These numbers are most
often given in base 16, or hexadecimal notation, but can also be
given as ordinary decimal (base 10) numbers. Keyboard layouts use the standard XML notation for describing such code points. A code point is in one of the following forms: • &#xnnnn; • &#nnnn; The first form is hexadecimal, and the number represented as nnnn is a hexadecimal number, containing digits 0-9, and letters A-F or a-f. Leading zeros are optional. The second form is decimal, and the number represented as nnnn is a decimal number, containing digits 0-9. Some examples: α represents the Unicode character “Greek small letter alpha”, α. α also represents α, as decimal rather than hexadecimal. ⼢ represents the Unicode character “Kangxi radical go slowly”, ⼢.   represents the space character. |
