Description of problem: Keymap needed for ZWJ in itrans key layout for Kannada(kn_IN) Version-Release number of selected component (if applicable): m17n-db-kannada
I would suggest "shift+v" as ZWJ for this, as it has not been allocated to any kannada character..
I saw that upstream is already added ZWNJ(U200C) and ZWJ(U200D) in kn-itrans.mim, therefore closing this as NOTABUG.
