Hi Donald,
You seem to be confused. You need to read my email again.
I explicitly stated that:
0d80-0dff (hereby referred to as Set A1, A2 and A3)
and
200C-200D (hereby referred to as Set B)
allows us to encode the Sinhala letters.
...
In our case it is roughly the union of:
This union produces a set of encodings containing all the basic elements (letters).
So once you understand and acknowledge the existence of Set C and D, then we can continue our discussion. If you do not understand the mathematical terms, please tell me, and I'll find an explanation for you.
What you wrote in your email does not even remotely correspond to what I wrote. I have taken the liberty to attach my email to the bottom of this email, as you seem to have replied to Anuradha's email and not mine.
Regards,
Harshula

Hi Donald,
You seem to be quite certain that you have not misunderstood the issue. On the other hand, I feel that you have. I'm more than happy to have a discussion, if and only if, we restrict the discussion to only the Unicode code chart.
I assert that the Unicode code range:
0d80-0dff (hereby referred to as Set A1, A2 and A3)
and
200C-200D (hereby referred to as Set B)
allows us to encode the Sinhala letters. If you disagree, please attach an image of the word that you claim can not be encoded. And I will attempt to give you the Unicode code sequence. We'll discuss only one word at a time.
First and foremost, you are getting bogged down by conceptualising letter encoding as a simple matrix. Perhaps this was the case a few decades ago, but it is no longer the case.
For extensibility purposes, the Unicode encoding ends up involving more than one simple matrix. In our case it is roughly the union of:
This union produces a set of encodings containing all the basic elements (letters). Ironically, this union not only contains your 1660 letters, it also includes baendi akuru. You should also note that the basic elements are not encoded by a fixed number of bits.
For the reasons stated above, it is incorrect to claim that the Unicode Sinhala encoding is incomplete.
You may also be interested in the UTF-8 encoding format which allocates a set of characters to be encoded in 8 bit, a larger set of characters to be encoded in 16 bits and an even larger set of characters to be encoded in 24 bits. Please note the use of dead high bits, I suspect it will become relevant later in the discussion: http://en.wikipedia.org/wiki/UTF-8

Harshula
