Change default <math> display to utilise "MathML with SVG or PNG fallback" at English Wikisource
Closed, DuplicatePublic

Description

At English Wikisource we are having issues that the default display for users logged in, and logged out is the PNG images setting and that is not helpful for display of transcribed pages.

eg. https://en.wikisource.org/wiki/Page:Radio-active_substances.djvu/49

Gives errors in PNG and sometimes in Latex

Browser statistics show that users are using more modern browsers, so it seems preferable to have the default to the modern display of math, and allow users to rollback to the other preference if they so choose.

"Traditionally" (by which I mean at least for the last couple of years) \mbox{} has not accepted most Unicode content and instead thrown the errors originally detailed.

I am more concerned that the parsing and validation under various modes appears to be inconsistent; either PNG mode is rejecting input which it ought to be capable of handling, or MathML is not validating sufficiently stringently and simply "hoping" the browser can cope with whatever unverified rubbish is being hurled at it. Neither seems particularly optimal?

Are we able to get the change made, or is there a technical reason that the configuration cannot be updated for the default?
