collating sequence mapping.

[Vibha R]

Hi all

We were designing a tool that would map from unicode to an internal code
..we thought the criterion for mapping would be the collating sequence
as it is language specific rather than the encoding system.
the problem we are facing now is that the collating sequences of the two
methods of encoding are different.
Is there any other way in which we can match or map the two systems of
encoding.

thanks..
