[Tex/LaTex] Counting characters in a section of a document


Is there a way to count characters in a document portion? I need to write a summary that is 3000 characters long at most, and every time I compile the document I copy/paste the resulting text to Word to do the count.
I found this post but it seems that solution doesn't work. What I would like to have is something like:

  % write here all the text

if characterCounter > threshold:
    {\color{red} Character count exceeded! }

TeXcount is your friend. It is a perl script for counting words in LaTeX documents. Although the ouput is a separate plain text file, you can include easily verbatim in the own LaTeX document without modify the result, because you can count any arbitrary chunks of text and avoid some parts using the pseudoenvironment comments %TC:ignore ... %TC:endignore. Moreover, you can obtain subcounts at some section levels and separate counts of words for main text, headers, captions, inlined math and displayed math (and more, although this is out of the question. Run texdoc texcount for more information).


% Compile with  --enable-write18 or --shell-escape options   
\immediate\write18{texcount -tex -sum \jobname.tex > /tmp/wordcount.tex}
\section[Count-me]{Count me}
This section is counted.  The quick brown fox jumps over the lazy dog. 
\section{Ignore me}
A litle ignored text in the count.
\subsection{This is a subsection}
And some text with inline math ($E=mc^2$).
\subsection{And this is another subsection}
And some more text with display math \[E=mc^2\]
\subsection{One more subsection with a float}
This part of the text include  one figure float.

To count characters instead of words, add simply the -char option after texcount:
