Unicode doesn have an “invisible letter” (INV) like ISCII. How can I form the combinations that use INV in ISCII?
There are four uses of Nukta in ISCII. Unicode only uses the first two. Unicode doesn’t use nukta for soft halant and doesn’t use it for code extension. Unicode does use nukta to represent the nukta diacritic either in cases such as “ka” U+0958 or cases like “nnna” U+0929. Unicode doesn’t use nukta for the “om” character (eg. chandrabindu + nukta in ISCII, which is encode as a separate character in Unicode).
