Hide part of the letters (LaTeX or LuaLaTeX)
The adjustbox
package provides ways to trim
and clip
boxed content:
\documentclass{article}
\usepackage{adjustbox}
\begin{document}
Horizontal hiding:
\begin{itemize}
\item --something--
\item --\phantom{some}thing--
\item --some\hphantom{thing}--
\item --\adjustbox{trim=0pt 0pt 17pt 0pt,clip,lap=\width}{something}\phantom{something}--
\item --\phantom{something}\adjustbox{trim=.3333\width{} 0pt 0pt 0pt,clip,lap=-\width}{something}--
\end{itemize}
Vertical hiding:
\begin{itemize}
\item --something--
\item --so\adjustbox{trim=0pt 3pt 0pt 0pt,clip,raise=3pt}{methi}ng--
\item --\adjustbox{trim=0pt 0pt 0pt .45\height,clip}{something}--
\end{itemize}
\end{document}

\end{scope}

\node[inner sep=0pt] (d) {\LaTeX};
\fill[white] (d.south west) rectangle (d.east);
\end{scope}
\end{tikzpicture}

Update
I've updated the code and defined several styles which can be easily applied to any text. Of course, these styles are just examples of what can be done.
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,calc}
\usepackage{lmodern}
\tikzset{
show bottom/.style={inner sep=0pt,
prefix after command={%
\pgfextra
\clip (\tikzlastnode.south west) rectangle ($(\tikzlastnode.south east)!#1!(\tikzlastnode.north east)$);
\endpgfextra}
},
show top/.style={inner sep=0pt,
prefix after command={%
\pgfextra
\clip (\tikzlastnode.north west) rectangle ($(\tikzlastnode.north east)!#1!(\tikzlastnode.south east)$);
\endpgfextra}
},
show left/.style={inner sep=0pt,
alias=this,
prefix after command={%
\pgfextra
\clip (\tikzlastnode.north west) rectangle ($(\tikzlastnode.south west)!#1!(\tikzlastnode.south east)$);
\endpgfextra}
},
show right/.style={inner sep=0pt,
prefix after command={%
\pgfextra
\clip ($(\tikzlastnode.north west)!#1!(\tikzlastnode.north east)$) rectangle (\tikzlastnode.south east);
\endpgfextra}
},
show bottom triangle/.style={inner sep=0pt,

\endpgfextra}

prefix after command={%
\pgfextra
\clip (\tikzlastnode.north west)--(\tikzlastnode.south)-- (\tikzlastnode.north east) -- cycle;
\endpgfextra}

show inner/.style={inner sep=0pt,
