== Special code points ==

; {{anchor|INV}}INV character—code point D9 (217): The INV (invisible consonant) character is used as a pseudo-consonant to display combining elements in isolation. For example, क (ka) + ् (halant) + INV = क्‍ (half ka). The Unicode equivalent is {{unichar|200D|ZERO WIDTH JOINER}} ({{ctrl|ZWJ}}). However, as noted [[#virama|below]], the ISCII halenthalant character can also be doubled or combined with the ISCII nukta to achieve {{ctrl|ZWNJ}} or ZWJ effects. For this reason, [[Apple Inc|Apple]] maps the ISCII INV character to the Unicode {{ctrl|LRM|left-to-right mark}}, so as to guarantee [[round-trip format conversion|round-tripping]].<ref>{{cite web |url=https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/DEVANAGA.TXT |title=Map (external version) from Mac OS Devanagari encoding to Unicode 2.1 and later. |author=Apple |author-link=Apple Inc |publisher=[[Unicode Consortium]] |date=2005-04-05 |orig-year=1998-02-05}}</ref>

; {{anchor|ATR}}ATR character—code point EF (239): The ATR (attribute) character followed by a byte code is used to switch to a different font attribute (such as bold) or to a different ISCII or [[PASCII]] language (such as Bengali), up to the next ATR sequence or the end of the line. This has no direct Unicode equivalent, as font attributes are not part of Unicode, and each script has a distinct set of code points.
