For example, the two strings /हिन्दी/ and /हिन्दी/ are identical to look at, but they differ in that the latter has a ZWJ between the न् and the द.
The problem is that certain “half-consonant” + “full-consonant” conjuncts require the ZWJ in order to prevent a ‘full conjunct’ form from occurring (e.g. /क्त/ as /क्त/). The only way to prevent the full conjunct form is to insert the ZWJ.
But in the “न् plus द” case, there is no more conjunct form than that. So both with and without the ZWJ gives the same presentation result.
This means that ultimately, the ZWJ is unnecessary in some cases of “half-plus-full” conjuncts, but it is necessary in others (i.e. /क्त/).
The keyboard I use has a key to press to get ‘half-consonants’ (i.e. by inserting both the halant and the ZWJ, since that is what is required in the “harder” case). The problem is I use it also to get the half-न even though in that particular case, it isn’t necessary. But a colleague is using the 'halant-only' key, since the ZWJ is not technically necessary in this case. The result is that the software thinks the two strings are different.
Having the software think this, is, first of all, a real hassle, since most users can’t tell the difference between the two and won’t know why the software thinks they're different.
So I have two questions:
1) What does your keyboard do in this respect when typing "half+full" consonant conjuncts? Do you only use the ZWJ where it is absolutely necessary (i.e. /क्त/, but not /न्द/).
2) If different, what do you think it ought to do?
Thanks,
