@iqbalhafidh After some investigation, I found that it's a konwn bug of MathJax on Android WebView. The native WebView failed to read the provided .woff fonts correctly and the issue remains unsolved in the latest official version of MathJax.

Fortunately someone came up with a solution. I have already replaced the .woff font files with tweaked .otf files and pushed an updated version of MathView to jcenter. You can switch the dependency version to 0.0.2 (compile 'io.github.kexanie.library:MathView:0.0.2'). The character 'A' should be normal now.
