What's a feature without a use case? Please provide a reason why.
One use case: people want to convert/create Unicode character from its code number.
For example, by typing '\u0D05\' it should be converted to 'അ'. Please see the code change for Malayalam transliteration in the commit, that function implements it.
Also callbacks can be used to combine several rules those share some behavior.
While writing the rules for some languages, I had met with rules that would have more tuned if this feature used. So this feature was in my mind from almost beginning of Narayam but just now only it got implemented.

hexcode based inputting does not seem to be a valid usecase here. It is very advanced and it is for people know the hexcode of characters.
['\\\\u([0-9a-fA-F]{4})\\\\', '', narayam_ml_unicode_char_convert], // use callback
Here the conversion is nothing specific to Malayalam, because we allow any 4 character length hexcodes. Moreover the length 4 rule is unnecessary.
All operating systems allow direct unicode inputting. See http://en.wikipedia.org/wiki/Unicode_input#Hexadecimal_code_input. In Gnome, I can type using hexadecimal characters by control+shift+ u + <hexcode>.
Also callbacks can be used to combine several rules those share some behavior.
I agree here. Do you have any patters where this can be used?

It is not a necessary to have there.

That I have to examine over the existing rulesets.
Anyway the callback feature is a must have in Narayam. Its implementation, programming logic, method signature can be tuned.
Junaid: Are you still working on this? If not, please reset this bug report's ASSIGNED status and/or the assignee person. Thanks!
