When compiling the following MWE, it generates messages such as
warning --- File `lm-ec.htf' starts/ends with character code 255 (instead of 124) warning --- File `lm-ec.htf' starts/ends with character code 255 (instead of 124) warning --- Couldn't find font `zxlri-8r.htf' (char codes: 17--181) --- Couldn't find font `zxlr-8r.htf' (char codes: 17--181) etc.. But when looking at the HTML output, there does not seem to anything wrong really with the output (such as in mangled letters or dropped "fi" and such) I understand these come out because tex4ht does not have full support for the fonts. But how come the HTML output looks fine when looking at it? Or does it mean one simply did not yet encounter the font problem because the current text being compiled does not have a text that will show the problem? I am just trying to decide if I should not use this font when seeing such warnings, even though the HTML output looks OK. ------------ MWE ------- \documentclass{article} \usepackage[T1]{fontenc} \usepackage{ntheorem} \newtheorem{theorem}{Theorem} \usepackage[libertine]{newtxmath} \DeclareMathOperator{\Res}{Res} \usepackage[english]{babel} \usepackage{blindtext} \begin{document} \blindtext \pagestyle{empty} \begin{theorem}[Residue Theorem] Let $f$ be analytic in the region $G$ except for the isolated singularities $a_1,a_2,\dots,a_m$.
