Complete mapping from W*dings to Unicode

[Crissov]

All characters from Webdings and Wingdings 1–3 have canonical mappings to Unicode, see e.g. Alan Wood's Unicode resources or Unicode document L2/12-368 = ISO/IEC WG2 N4384. Some of them are also emojis now, some of which need VS-16 U+FE0F attatched to be displayed with colors (or VS-15 U+FE0E to stay monochrome). Even if most of these are rarely send by Outlook users, I think it still makes sense to supply all of these mappings by default.
