I will try to summarise the issue. Malayalam has a set of characters
called "chillu" (or pure consonants) which are not basic characters
but derivatives of the basic characters and so they don't have a
codepoint in unicode as of now.

So to render these characters unicode special character ZWJ is used.
So if you want to create a "chillu" then what you do is use a
combination of the base consonant (has a codepoint in the range
allotted to Malayalam) + halant (again has a codepoint in the range
allotted to Malayalam) +  ZWJ (unicode special character u+200d and
which is not in the range of Malayalalam). I think many other
languages also use ZWJ for example see this
http://www.laits.utexas.edu/persian/persianword/zwj.htm

In the same way to prevent conjunct formation ZWNJ (u+200c) is used.
So I guess the issue can be solved if Malayalam is allowed to have ZWJ
and ZWNJ (and sometimes ZWS but rare).

Let me know if anything is not clear.

Users know of these as the keyboard layout has positions for these
characters and transliteration input methods use _,~ to use this.

Would it be possible to give exceptions for this characters for Malayalam?
