Vertical line superimposed over a letter

Question

Looking for a way to put a vertical line over another character. Similar to the \cancel feature, but with a vertical, rather than a slanted line. For example on a capital S the vertical line would turn it into something akin to a US dollar symbol: $. (verticallity in this text box seems dependent upon font choice) i.e. superimpose a | over a C

While you could use \newcommand{\vertchar}[1]{\ooalign{#1\cr\hidewidth$|$\hidewidth}} with \vertchar{s} and \vertchar{c} (say), it doesn't really look nice with \vertchar{S} and \vertchar{C}. Could you be specific in terms of your actual usage? — Werner, May 21 '14 at 18:34
Usage is in a review article I'm typing for a prof. The hand written symbol looks like the two vert/C's in Oberdiek's example below. I was able to make the \mathclap command work, actually coupled with a \mathcal to achieve an agreeable symbol. This does tend to crowd a preceding (, but adding \hspace*(.01in) spaced things nicely. I'm going to experiment with the others shown here. Thanks Swann. — TommyK, May 22 '14 at 13:28

The following solution uses TikZ (more configuration options as rounded line caps, ...). The optional argument of \vertchar allows horizontal fine tuning:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\newcommand*{\vertchar}[2][0pt]{%
  \tikz[
    inner sep=0pt,
    shorten >=-.15ex,
    shorten <=-.15ex,
    line cap=round,
    baseline=(c.base),
  ]\draw
    (0,0) node (c) {#2}
    ($(c.south)+(#1,0)$) -- ($(c.north)+(#1,0)$);%
}
\begin{document}
  \vertchar{S} and \vertchar{C} or \vertchar[.08ex]{C}
\end{document}

\stackinset allows you do do this with the syntax

\stackinset{H-anchor}{H-offset}{V-anchor}{V-offset}{inset}{base}

The inset and base can be glyphs, phrases, images, anything that can be set into a LaTeX box. The H-anchors are l, c, or r. The V-anchors are t, c, or b. You can stack math by default by issuing \stackMath, which is done for the 2nd example of the MWE, where I simulate an @ symbol by insetting a math a inside a math O.

\documentclass{article}
\usepackage{stackengine}
\begin{document}
\stackinset{c}{}{c}{}{\rule{.4pt}{2ex}}{C}
\stackMath
\stackinset{c}{}{b}{1pt}{a}{O}
\end{document}

enter image description here

The insets can be nested to inset multiple things over one base, such as in this answer: Mathematical formulas on a graph (not made by TeX)
