Any consonant should be able to become a half-consonant, but only when followed by another consonant. In the TTF method, character type checking falls out easily. I'm still up for your suggestion, which if I understand it correctly, is to take up parts of the unspecified unicode ranges and dedicate them to half-consonants? You would then have to do this for Bengali, Telugu, Tamil, Gujarati, Gurumukhi (I think), and perhaps a couple of others. It's the fastest implementation, but has a couple of set backs: (a) it is not homogeneous across all Plan 9 distributions, and (b) it diverts from general Unicode standards, and thus, the problem of reading texts is still present, as everyone else is still using the consonant+virama+consonant sequence as opposed to following our self-defined code maps. One can deal with (a) if dedicated enough to language support for a billion or so people, but (b) is pretty serious and still presents us with the same full-stop as before. If there were some way to map unicode sequences to our self-defined codes, then that could work in this methodology. kbmap perhaps? Best, ak
