Certain unicode characters do not show in chat or hover text in v7 viewers, but do in v6 viewers.

[canny]

I recently upgraded Firestorm from v6, noticed certain unicode characters in chat and hover text exhibit the bug, installed LL's viewer, saw the same issue.

I was told by Monty Linden in the last server meeting to file a bug report for the viewer to get a font pack update.

Here are a few out of many problem characters:

[2025/04/29 05:36:35] llOrd(textbox): llOrd('🗕',0) = 128469 (0x1f5d5)

[2025/04/29 05:36:46] llOrd(textbox): llOrd('🗙',0) = 128473 (0x1f5d9)

[2025/04/29 05:36:51] llOrd(textbox): llOrd('🞁',0) = 128897 (0x1f781)

Test plan:

• Paste the following line into chat or a script and see if they appear as an underline, an x, a triangle, a nope. triangle pointing right, triangle pointing left, triangle pointing up, triangle pointing down.
• '🗕','🗙','🞁', '🛇', ⯈ ⯇ ⯅ ⯆

The U+2BAF to U+2BC8 range appears to genuinely not be in our fonts. Notosans or inter might be needed for that.
As far as I can tell symbol 🛇 was never supported, it's red version was supported, but since out fonts didn't support colors it was drawn as black and now is properly red.
🗕🗙🞁 do not appear to be in our fonts as well. They are relatively new (when copared to our fonts) and can be found in Noto Sans

Check this again after we update fonts.

These characters are still unsupported by the 26.2.0.24476400809 viewer.

FWIW, these characters are not supported by the Chrome or FireFox web browsers on Mac either.
