Fwiw, on my OSX laptop, with whatever particular fonts I have installed there, using a particular webmail service in the particular browser I use, I see all six glyphs.

If I were to copy-paste into a text editor, all bets would be off, and depend on the editor and it its settings. Same for interactive shells run in particular terminal apps.

Viewing right now, on my Android tablet and the Gmail app, I see a bunch of missing glyph markers. But quite likely I could install fonts or change settings on this device to render them.
