(Please refer pages 83 and 84 of the pdf file attached earlier)
It would be helpful to include the tables in the order given below. It
would be highly desirable that they are enumerated NOT in the unicode
order but in their natural order (i.e., the order in which we are taught
to recite these alphabets in our schools)
High Usage Characters
=====================
+ Independent Vowels Table + Aytham [1]
This table will contain the 12 "Independent vowels" FOLLOWED BY the
letter "Aytham" (0B83). The unicode order for these alphabets
is the SAME as their natural order (leaving aside those marked reserved)
+ Consonants Table [2]
This table will contain 18 of the characters listed under
"Consonants". The unicode order for these is DIFFERENT from their
natural order (leaving aside those marked reserved)
Some 2D-table representation similar to the one listed under "Unicode
Tamil Syllabary" in the below URL could be used.
"http://en.wikipedia.org/wiki/Tamil_alphabet#Tamil_in_Unicode"
If that is not aesthetically pleasing, then just listing the Row and
Column Labels should suffice. Particularly, I like the fact that the
Vertical Labels (the Row Labels) in the above table use the base form of
Consonants - (i.e., Consonant devoid of it's trailing vowel `a' which
is represented by a "dot" on top of tamil character- I believe this is
achieved by using TAMIL SIGN VIRAMA)
The above two tables plus an an illustration of how to enter tamil text
should suffice to get the point across to the user. So some suggestion
along the lines of:
"To enter வணக்கம் type vaNakkam"
(The word used above is the "HELLO" entry for Tamil)
Medium Usage
============
+ Grantha Letters [3]
This table will contain the remaining 5 consonants + one compound
alphabet designated with input method 'x'.
- I see the letter 0BB6 as a rectangle. Not sure whether this is a bug
in Emacs or my local installation.
- I don't know how to enter the character - described as "common
ligature 'Sri' (ஸ்ரீ Śrī)" - As the Wikipedia entry clearly says it is
a commonly used character (equivalent to English "Sir/Madam").
(See "Usage of other lingual consonants" section under previously
referred to Wikipedia entry)
+ Various/Miscellaneous [4]
- Not sure what these are called. I have just called it
miscellaneuous.
+ Dependent Vowel Signs, Two-part dependent Vowel signs
- I find it difficult to relate to these characters with their
consonant component greyed out. These NEED NOT BE LISTED as part of
the help text.
The tables listed below are mostly of interest to very niche users like
language scholars or for traditional uses like local calendars, marriage
invitations, temple festivals etc. They are not used by a layman for
day-to-day communication. In some sense they could be given low
priority. Honestly, speaking I have never used them in my 35 years of
existence. So I don't have any fixed opinions on these. Listing them
here merely for the sake of completion.
Nice/Rare Usage
===============
+ Digits and Numerics [5]
- I find that I am unable to insert the following alphabets with M-x
ucs-insert. TAB completion doesn't offer these characters (they are
listed in the unicode table though)
- TAMIL NUMBER TEN
- TAMIL NUMBER ONE HUNDRED
- TAMIL NUMBER ONE THOUSAND
Also I find that I am unable to ucs-insert TAMIL DIGIT ZERO. I am
not sure whether that is same the regular arabic/english `0'.
+ Tamil Symbols [6] (Tamil Symbols, Currency Symbol and Tamil Symbol)
- When I ucs-insert them, I only see rectangular boxes. Not sure
whether it is a problem with Emacs distribution or my local
installation. Just curious, how can I display these characters
within Emacs.
Additional Note: Currency symbol is something that I personally
recognize. May be it could be grouped under "Miscellaneous" table..
+ Reserved
- 0BE4, 0BE5
No idea what these characters are.
