TT, This article lists glyphs supported by an intersection of a set of fonts <https://www.johndcook.com/blog/2013/04/11/which-unicode-characters-can-you-depend-on/>. Perhaps we could take this list and present it in a tiddler, in a large font size and put it out to the user forum for people to test and report if all the glyphs are visible. Perhaps also in an empty.html at a URL people can just open an review on their various devices?
Here is my initial draft Glyphs 5.1.23-prerelease — Identifying reliable Unicode Glyphs on TiddlyWiki Build Date (anthonymuscio.github.io) <https://anthonymuscio.github.io/PreReleaseGlyphs.html> So far up looking at to 65000 on Windows 10 (Chrome, FireFox and Edge) most are honoured however I have various local fonts that may be doing this. Android also works mostly.
