Details:

Error reported by Nasser M. Abbasi on TeX.SX [1]

This code:

\documentclass[]{article}%
\usepackage{amsmath}   
\begin{document}  
$\uparrow\sum F$
\end{document}

results in error 

! Bad mathchar (79119).   & \uparrow \sum F 
   l.8 \end{align}
?

with mathml output. As pointed out by Enrico Gregorio, this is caused by
passing parameters \mathchar without terminating with space or \relax. This
may cause weird behavior like in Nasser's example, when \sum F results in
\mathchar"1350 F and because F is proper hexadecimal number it is added.
Enrico proposed solution and I've made a patch for fixing this issue.
