Summary: Bad mathchar (79119) using htlatex+mathml with \uparrow with align from amsmath package Project: tex4ht Submitted by: michal_h21 Submitted on: Tue 16 Sep 2014 10:36:41 PM EEST Category: None Priority: 5 - Normal Severity: 5 - Normal Status: None Privacy: Public Assigned to: None Originator Email: Open/Closed: Open Discussion Lock: Any _______________________________________________________ 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). <argument> & \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.
