in malayalam there are two inscript layout are there, one is inscript (inscript 1) another is enhanced inscript (inscript 2). in enhanced inscript zwnj is missing. it was assigned in \ key in inscript 1. now the key is assigned to another malayalam chillu “ർ”. in standard inscript 2 the zwj key should be in Ext 1 and zwnj should be in Ext 2 keys.
so the needed changes are
assign ext 1 - zwj
assign ext 2 - zwnj
may be we can keep zwj in ] too but multiple mapping for single glyph is not a good idea.
here is the issue
people are familiar with ] as zwnj.
now moving to Ext 1 will be pain for users, so shall we just add zwnj in ext 2 ?
please comment your opinion, we have to fix this.
