(input-method kn itrans)

(description "Kannada input method by ITRANS, Baraha and Harvard-Kyoto
transliteration systems.
You can use all the standard ITRANS key sequences plus key
sequences such as the below.

nk->ಂಕ್, nkh->ಂಖ್, ng->ಂಗ್, ngh->ಂಘ್
nch->ಂಚ್, nCh->ಂಛ್, nc->ಂಚ್, nC->ಂಛ್, nchh->ಂಛ್,
nj->ಂಜ್, njh->ಂಝ್, nT->ಂಟ್, nTh->ಂಠ್, nD->ಂಡ್, nDh->ಂಢ್
c->ಚ್, C->ಛ್, z->ಶ್, S->ಷ್, jn->ಜ್ಞ್, R->ಋ

The motivation behind additions made to the basic ITRANS scheme
is described in https://sanskrit-coders.github.io/input/optitrans/,
along with a tabulated comparison with several other
transliteration schemes.
