Dear Sasi
Thanks for that

This is because there was no standard for displaying the text. Each font could be created according to the whims and fancies of the person who created the font.
That is why we cannot, for example, read Mathrubhoomi even if we have
the Manorama font. By defining a standard manner in which the text can
be encoded without the characters of two languages overlapping,
Unicode has solved the problem so that even files and folders can be
named in any language

But this problem is existing with English too
The fancy font used by a third party will not show it in your computer if you don't have that particular font. text will converted to default font.

One more question
Is all the Keyboard same?
If I learn to type in the typesetting softwares Keyboard format can I type in the unicode fonts too?
I mean the encoding is going how? are the code writiers have a common style for writing codes for fonts?

Though I am not an expert in this matter, may I try to explain this
slightly differently? As you know, all information in a computer is
represented using 1s and 0s. These are generally used in groups of 8
or 16 or 32, like 01010101 or 1010101010101010. Now, how each
character is represented in a computer is determined by the kind of
code used. For instance, the American Code for Information Interchange
(ASCII - see http://en.wikipedia.org/wiki/ASCII) defines 1000001 as A.
The next number in this sequence, namely 1000010, is defined as B.
Similarly, all upper case and lower case characters, the numerals 0 to
9, punctuation marks like :, ", etc. are also defined in terms of 0s
and 1`s. ASCII uses strings of only 8 characters. Therefore, it can
represent only a maximum of 256 characters. This was okay initially
because it was only English and some European languages that were used
on computers. When it became necessary to use more languages,
something different had to be done. That is how Unicode was developed.
Now, I hope you see how characters are represented in a computer. Now
it is the question of how these characters can be input into the
computer from a keyboard. This is determined by how the keyboard is
defined. The keyboard transfers a code when a key is pressed. The
keyboard definition determines what code the computer interprets this
as. If it is ASCII, we see ASCII characters on the screen. What we see
on the screen also depends on what is the font used. For example, we
can represent the same character using many different fonts, as you
know. Now, in earlier days, many languages like Malayalam and Hindi
used to be displayed on the screen (and also printed) using fonts that
manipulated ASCII to show something else. The problem in this system
is that we cannot do many things in that language (for example,
sorting) and how the text is displayed depends on the particular font
used when entering the text so that the person who wants to read it on
another computer should have the same font. This is because there was
no standard for displaying the text. Each font could be created
according to the whims and fancies of the person who created the font.
That is why we cannot, for example, read Mathrubhoomi even if we have
the Manorama font. By defining a standard manner in which the text can
be encoded without the characters of two languages overlapping,
Unicode has solved the problem so that even files and folders can be
named in any language. Hope I have not distorted anything while trying
to simplify the ideas. I think you can get a more complete idea by
reading this together with what Mahesh has written.
