: Sir,
The planes 03 to 13 (03 to D) are vacant.
These planes may be thought of, for Syllabary languages, to allot code spaces exclusively for syllables, so that the computing skill of these languages improves substantially, in as much as the definition of alphabet includes syllables also. (vide core specification 4.10: the Unicode Standard includes various “alphabets” and “syllabaries,” it also includes writing systems that fall somewhere in between. As a result, no attempt is made to draw a sharp property distinction between letters and syllables)
At present, these languages suffer a lot by spending memory, enormously, for each syllable [3 bytes (base alphabet) + 3 bytes (vowel sign or diacritic or combining character) + 1 to 3 bytes for instructions to combine them, 7 to 10 bytes for each syllable]
This can be avoided and made memory efficient for Indic languages (for example) by allotting code spaces to Indic Syllables and later deprecating the redundant vowel signs, diacritics, combined characters and the these languages made computer skilled.
The ISO is expected to guide the Unicode Consortium to take suitable action in this regard for syllabic Languages, making use of vacant planes.
The Government of India and other Governments, in Asia, are to take necessary urgent action to approach the ISO / IEC and Unicode Consortium, to get code spaces for syllables of their languages, making use of vacant planes.
The Unicode Consortium is also expected to test and remove the bugs, if exists, and satisfy the vacant planes are bug proof D
