take 'ksha' -> ka halant sha, is a ligature. The lookup for this ligature

why would you want to place a ZWJ to join ka & sha?
To indicate that they are joined, as opposed to separate.
I have never come
across a unicode script which uses ZWJ to indicate how *every* adjacent
characters should be joined.
That's because the people who did unicode encoding thought that Hindi
was the standard, and did not take into account languages like Sinhala,
Tamil, Malayalam, Telugu, etc.
Quoted from opentype spec by adobe :

SLS1134 is not dependent on OpenType. We don't want to be tied to the
(very incomplete) feature provided by OpeType.
Whether you want a pure consonant (without a vowel) to be written
touching the next letter, joined to the next letter, or with an explicit
al-lakuna, is your writing style, and independent of the language used.
The whole point is you should not encode style.
I think most people are very keen that the user see what they expect,
and we do not want to leave it to word processor, browser or font
dependent features to provide this.
SLS1134 supports all three writing styles, and you can mix them in the
same document so an author can get the effect he wants.
As you correctly said, Pali & Sanscrit are writing *styles*, therefore IMHO
should be handled by a layer on top of encoding.
This is certainly possible, but I think that it is better to do it at
the encoding level. Otherwise there will be no interoperability (this
is called the "yakshaya" syndrome).
It will be forwarded as a tech note.
that means we dont have to buy a copy of SLS 1134? Super!!!
It has been available on fonts.lk for a while.
