Inserting character 'க்ஷ' in GNU Emacs

Inserting character 'க்ஷ' in GNU Emacs

[Shakthi Kannan]

Hi,

I have fonts-lohit-taml-classical installed on Ubuntu 14.10. I am
trying to input the character 'க்ஷ' in GNU Emacs 24.5.1. This
character is a combination of 'க' and 'ஷ' which are the only
characters available in Tamil Unicode.

  http://unicode.org/charts/PDF/U0B80.pdf

If I copy this character 'க்ஷ' from a UTF-8 website and insert the
same in a file (say, test.txt) using Gedit, it copies fine. I use
Monospace font. I am able to open the same file in GNU Emacs, and it
shows the character as 'க்ஷ'. Using C-u C-x = in this character
displays the following:

=== க்ஷ viewed in GNU Emacs ===

             position: 2101 of 2106 (100%), column: 0
            character: க (displayed as க) (codepoint 2965, #o5625, #xb95)
    preferred charset: unicode-bmp (Unicode Basic Multilingual Plane
(U+0000..U+FFFF))
code point in charset: 0x0B95
               script: tamil
               syntax: w which means: word
             category: .:Base, L:Left-to-right (strong)
             to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
          buffer code: #xE0 #xAE #x95
            file code: #xE0 #xAE #x95 (encoded by coding system utf-8)
              display: composed to form "க்ஷ" (see below)

Composed with the following character(s) "்ஷ" using this font:
  xft:-unknown-Lohit Tamil
Classical-normal-normal-normal-*-17-*-*-*-*-0-iso10646-1
by these glyphs:
  [0 2 0 217 24 -1 22 8 4 nil]

Character code properties: customize what to show
  name: TAMIL LETTER KA
  general-category: Lo (Letter, Other)
  decomposition: (2965) ('க')

There are text properties here:
  fontified            t

=== END ===

How can I input this character directly in GNU Emacs? I have a custom
layout defined using quail:

Appreciate any help in this regard,

Thanks!

It's not one character, it's 3 characters that get displayed as a
single "grapheme cluster".  The "Composed with" sentence above shows
you the other 2 characters.  You need to type them all, one after the
other.  One way to type them is also shown: "C-x 8 RET" followed by
the hex code or name of the character (e.g., "TAMIL LETTER KA").

I typed "க", "்" and "ஷ" in succession, and it worked.

Thanks!
