As mentioned in the first section, itrans makes use of only a subset of the ligatures available in the Devnag font. itrans only recognizes two-consonant ligatures, and most ligature of more than two consonants is ignored.
The two tables (in tables 4 and 5) display the ligatures that are being used in ITRANS. All the ra-consonant and consonant-ra ligatures are not displayed in the available list, but they are handled by itrans correctly.
Table 6 displays ligatures that are not used, along with their decimal character codes (glyph positions).
ITRANS versions 5.1 and newer do support three- or more consonant conjuncts, so, it is technically possible to support all these conjuncts, but to keep things simple, I am currently simply ignoring these complex glyphs. If there are a few conjuncts that are important enough to be included, let me know, and will add those definitions to the dvng.ifm file. I have added a few such conjuncts to dvng.ifm and dvngfull.ifm files, the tables 4 and 5 show all supported conjuncts.
