We still use regular expressions to escape invalid XML characters to entities, so it works only with LaTeX.
+But regular expressions may be slow if there is a huge number of math, and they may fail if contents
+of any math environment is larger than 64 KB.
+So we provide a "fastmathjax" option, that doesn't do any post-processing of the math contents. It should
+result in 60-70\% speed-up. The downside is that if math contains characters that are invalid in the
+XML mode, such as ampersand, less-than and greater-than, make4ht XML DOM filters will fail. Fortunatelly,
+make4ht will then switch to the HTML parser mode, so DOM filters will be still executed.
