Thank you Ross and others.
In fact, \kok is what I need. I need it to implement the Kashida option
in xepersian that I will post my implementation this week in a separate
email.

Hi all,
Is it possible to construct a box that contains a fraction (say half)
of a character (horizontal half) of a font.
It isn't clear whether you want the width of the box
to be the original character width, or only the width
of what remains visible after knocking-out half of it.
Here are commands which implement both viewpoints,
with an optional parameter to adjust how much to
"knock out" (i.e., overprint with a white rule).
The examples test various amounts.
\usepackage{color}
\newcommand{\ko}[2][.25]{{#2%
\setbox0=\hbox{#2}\dimen0=#1\wd0
\dimen2=\ifdim \dp0=0pt .1ex\else 1.1\dp0\fi
\kern-\dimen0
{\color{white}\vrule height 1.1\ht0 depth\dimen2 width\dimen0}%
% \kern-\dimen0
}}
\newcommand{\kok}[2][.25]{{#2%
\setbox0=\hbox{#2}\dimen0=#1\wd0
\dimen2=\ifdim \dp0=0pt .1ex\else 1.1\dp0\fi
\kern-\dimen0
{\color{white}\vrule height 1.1\ht0 depth\dimen2 width\dimen0}%
\kern-\dimen0
}}
\begin{document}
