Virama + ZWJ      ^ (Caret)

ZWNJ                  |   (Pipe) 

( Use ~ as a escape character to get the above three characters again i.e ^~ to get ^ )

These Control Character can be used to manipulate the ligature formation in Grantha, enabling to choose alternate Conjuncts other than the default ones.

| breaks the formation of Conjuncts, while ^ can be used to form stacks instead of combining ligatures.
