'pasted string' and 'number of rawcode character' (19) looks different from one
which reported in description of problem

The Unicode character sequences given only in the initial "Description of
Problem" are correct. Everywhere else 19 characters are mentioned.

The real problem is of split matra. The 10th character U+0D4B, is split into
two characters, U+0D47 and U+0D3E at the time of rendering, which is adding to
the extra backspace.

This does not harm the usability in any way, hence this should not be
considered as a bug, unless there is an authentic report of the script
behaviour given by any user of the script.

there is problem with pango
its doing normalization of 0d4a  kind of characters into

0d46 + od3e
so while backspacing it takes one extra space

there are some bug files for same thing, i will try to find such bug and close
this one

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Yes, This is fixed now !!

step to check

1) enter Unicode 0D4A with ibus-rawcode or any other method
2) press backspace
3) complete character getting deleted (earlier it was required two backspaces)
