Sourav,
I am a little unsure of what your last question means.
Here's my stab at an answer for you.

1) Yes, Java uses Unicode internally and therefore files in other
encodings need to be converted.

2) Whether the OS supports Unicode is irrelevant, since Java can provide
the conversion on its own. However, although Win 95, 98 are not fully
Unicode, the OS does support encoding conversions to/from Unicode.

3) Since Java requires Unicode for its character processing, why ask
about not converting?
If you are asking whether it wouldn't be better for Java to not require
Unicode be used internally, the answer is no.
If Java supported other encodings internally, all of the text-based
functions would have to be implemented multiple times to accomodate the
different encodings and their processing requirements. It would take
much longer to produce Java environments for each platform and the sum
of Java's functionality would would not have been created so quickly.
And it would be much less portable.
