In Unicode, a sequence like:
simply represents a sequence of two ka's (pronounced, I guess, "kaka").
If you want to spell "kka", you should use the sequence:
U+0D15 U+0D4D U+0D15
Where U+0D4D is Malayalam virama (or halant?). But good-quality application
should not actually show the virama: the whole 3-character sequence should
be substituted with the glyph for "kka". (This is not encoded as a separate
Unicode character, but should nevertheless be a specific glyph in a
When you actually want the virama sign to be shown, I think you should use
U+0D15 U+0D4D U+200C U+0D15
U+200C is a control character called "zero width non joiner" or "ZWNJ"
(pronounced "zweenj") that is used for several purposes in different
scripts. For Indic scripts like Malayalam, it has the meaning to "reveal"
viramas that should normally be invisible.
(I am not totally sure about this U+200C; especially, I don't remember if it
goes before or after U+0D4D. but other readers may correct me).
I think that this policy to use virama to build composed consonants is not
specific to Unicode: if I remember well, the mechanism is taken from ISCII,
an 8-bit Indian character set.
I hope this helps.
