  \charcount{12 34}\typeout{\thecharcnt}

To typeset the result, use \arabic{charcnt}.

Note that the macro counts tokens, not characters.  Since a control
sequence name is one token, \charcount{180\textdegree} will return 4.

The macro \@tforloop is defined in the LaTeX sources, file ltcntrl.dtx.

The macros \makeatletter and \makeatother temporarily allow @ in
command sequence names.  They have to be removed if you put the macro
definition into a .sty file.

\charcount doesn't work with \usepackage[utf8]{inputenc}.  It returns
the number of bytes of multibyte characters.  But if you need Unicode
you can try Omega or Aleph instead of TeX.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
