I compiled a tex code by tex4ebook, and it seems to me that the symbol ⊈ is not rendered correctly by ebook-viewer in calibre. I write a test code and use htlatex to compile it into html (see the code below), and load it with ebook-viewer. It seems to me that the piece of code
Code:
<span class="msbm-10">⊈ </span>
is not rendered correctly, seemingly a font configure problem. I changed the font from DejaVu Serif to something else, the problem remains.
However, firefox and FBReader render it properly. I wonder how to fix it. Thanks for suggestions.
