+;;; Functions for composing Tibetan character.
+;;;
+;;; A Tibetan syllable is typically structured as follows:
+;;;
+;;;      [Prefix] C [C+] V [M] [Suffix [Post suffix]]
+;;;
+;;; where C's are all vertically stacked, V appears below or above
+;;; consonant cluster and M is always put above the C[C+]V combination.
+;;; (Sanskrit visarga, though it is a vowel modifier, is considered
+;;;  to be a punctuation.)
+;;;
+;;; Here are examples of the words "bsgrubs" and "h'uM"
+;;;
+;;;            $(7"72%q`"U1"7"G(B         2$(7"H`#A`"U0"_1(B        
+;;;
+;;;                             M
+;;;             b s b s         h
+;;;               g             '
+;;;               r             u
+;;;               u
+;;;
+;;; Consonants ''', 'w', 'y', 'r' take special forms when they are used
+;;; as subjoined consonant. Consonant 'r' takes another special form
+;;; when used as superjoined as in "rka", and so on, while it does not
+;;; change its form when conjoined with subjoined ''', 'w' or 'y'
+;;; as in "rwa", "rya".
+;;;
+;;;
+;;; As a Tibetan input method should avoid using conversion key,
+;;; we use a "Tibetan glyph -> transcription -> Tibetan glyph"
+;;; translation at each key input.
+;;;
+;;; 1st stage -  Check the preceding char.
+;;;              If the preceding char is Tibetan and composable, then
+;;;
+;;; 2nd stage -  Translate the preceding char into transcription
+;;;
+;;; 3rd stage -  Concatenate the transcription of preceding char
+;;;              and the current input key.
+;;;
+;;; 4th stage -  Re-translate the concatenated transcription into
+;;;              a sequence of Tibetan letters.
+;;;
+;;; 5th stage -  Convert leading consonants into one single precomposed char
+;;;              if possible.
+;;;
+;;; 6th stage -  Compose the consonants into one composite glyph.
+;;;
+;;; (If the current input is a vowel sign or a vowel modifier,
+;;;  then it is composed with preceding char without checking
+;;;  except when the preceding char is a punctuation or a digit.)
+;;;

+;;; This function is used to avoid composition
