Stacks & Ligatures
ZWJ _ (Underscore)
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.
nga & nja
The strokes nga and nja morph into Nasals as displayed in the Consonant keystrokes. To denote the conjunct of n & g , n & j use the strokes na^ga & na^ja respectively
They have to be formed via ZWJ.
(The above combination does not display properly [atleast] in Windows 7 with Office 2007. But it is being displayed properly other Windows 7 Applications like Wordpad, Notepad)
Please refer to the Grantha Manual of Indolipi for more detailed usage of these Control chracters to manipulate Grantha display.
