The ligatures for the Malayalam conjuncts ച്ച, ള്ള have less popular variants as shown below
The second form is not seen in print but often in handwritten Malayalam. I have seen it a lot in bus boards especially at Thiruvananthapuram. There are no digital typefaces with the second style, except the Chilanka font I designed. It uses the second variant of ച്ച. I got lot of appreciation for that style variant, but also recieved request for the first form of ച്ച. I had a private copy of Chilanka with that variant and had given to whoever requested. I also recieved some requests for the second style of ള്ള. For the Manjari font too, I recieved requests for second variant.
