-;; Indian script word contains one or more syllables.
-;; In BNF, it can be expressed as follows:
-;;
-;; Word ::= {Syllable} [Cons-Syllable]
-;; Syllable ::= Cons-Vowel-Syllable | Vowel-Syllable
-;; Vowel-Syllable ::= V[D]
-;; Cons-Vowel-Syllable ::= [Cons-Syllable] Full-Cons [M] [D]
-;; Cons-Syllable ::= [Pure-Cons] [Pure-Cons] [Pure-Cons] Pure-Cons
-;; Pure-Cons ::= Full-Cons H
-;; Full-Cons ::= C [N]
-;;
-;; {} repeat, [] optional
-;;
-;; C - Consonant ($(5!3!4!5!6!7!8!9!:!;!<!=!>!?!@!A!B!C!D!E(B
-;;                $(5!F!G!H!I!J!K!L!M!N!O!P!Q!R!S!T!U!V!W!X(B)
-;; N - Nukta ($(5!i(B)
-;; H - Halant($(5!h(B) or Virama
-;; V - Vowel ($(5!$!%!&!'!(!)!*!+!,!-!.!/!0!1!2#&#'#*(B)
-;;     ("$(5#&#'#*(B" can be obtained by IS13194 vowels with nukta.)
-;; D - Vowel Modifiers, i.e. Anuswar, Chandrabindu  ($(5!!!"(B) 
-;;     (Visaraga ($(5!#(B) is excluded.)
-;; M - Matra ($(5!Z![!\!]!^!_!`!a!b!c!d!e!f!g#K#L#M(B)
-;;     ("$(5#K#L#M(B" can be obtained by IS13194 matras with nukta.)
-;;
-;; In Emacs, one syllable of Indian language is considered to be one
-;; composite glyph.  If we expand the above expression for
-;; cons-vowel-syllable, it would be:
-;;
-;; [[C [N] H] [C [N] H] [C [N] H] C [N] H] C [N] [M] [D]
-;; 
-;; Therefore, in worst case, the one syllable may contain
-;; following characters.
-;;
-;; C N H C N H C N H C N H C N M D
-;;
-;; The example is a sanskrit word "kArtsnya", where five consecutive
-;; consonants appear.
-;;
-;; On the other hand, consonant-syllable, which appears at the end of 
-;; the word, would have the following expression:
-;;
-;; [C [N] H] [C [N] H] [C [N] H] C [N] H
-;;
-;; This is acceptable BEFORE proper consonant-syllable is input.  The
-;; string which doesn't match with the above expression is invalid and
-;; thus must be fixed.
-;;
-;; Note:
-;; Third case can be considered, which is acceptable syllable and can
-;; not add any code more.
-;;
-;; [[C [N] H] [C [N] H] [C [N] H] C [N] H] C [N] [M] D
-;;
-;; However, to make editing possible even in this condition, we will
-;; not consider about this case.
-;;
-;; Note:
-;; Currently, it seems that the only following consonants would have
-;; Nukta sign attatched.
-;; ($(5!3!4!5!:!?!@!I(B)
-;; Therefore, [$(5!3(B-$(5!X(B]$(5!i(B? can be re-written as

-;; => $(5!X![(B/$(5"F!D!\(B
-;;
-;; Then, determine the base glyph, apply-orders and apply-rules.

-;; => $(5!X(B (ml.mr) $(5![(B / $(5!D(B (ml.mr) $(5"F(B (mr ml) $(5!\(B
-;;
-;; Finally, convert 2-column glyphs to 1-column glyph

-;;
-;; => $(6![(B (ml.mr) $(6!X(B / $(6!D(B (ml.mr) $(6"F(B (mr ml) $(6!\(B
-;;
-;; Compose the glyph.
-;;
-;; => 2$(6!X@![1(B/2$(6!D@"FP!\1(B

-;;        RULES WILL BE EVALUATED FROM FIRST TO LAST.
