- ;; Step 0: Reordering Characters
- ;;
- ;; According to the Unicode canonical combining class value (CCCV),
- ;; Tibetan combining characters must be orderd in the following way:
- ;;
- ;; MARK HALANTA (CCCV=9)
- ;; VOWEL SIGN AA (129)
- ;; Above base vowel signs (130)
- ;; VOWEL SIGN U (132)
- ;; MARK TSA -PHRU (216)
- ;;
- ;; However, the current font expects the following order:
- ;;
- ;; MARK TSA -PHRU
- ;; VOWEL SIGN AA
- ;; VOWEL SIGN U
- ;; MARK HALANTA
- ;; Above base vowel signs
