; Numbers are always sorted in numeric order. Letters are first
; sorted without regard to case; when words are identical, the
; uppercase version precedes its lowercase counterpart.
;
; A special symbol is defined here to be any character not appearing
; in the union of digits and the English alphabetic characters.
; Patterns starting with special symbols precede numbers, which
; precede patterns starting with letters. As a special case, a string
; starting with a digit but mixed with non-digits is considered to be
; a pattern starting with a special character.
