NO MORE □ — MASTERING EMOJI ON ANDROID
summary
Explains practical fixes and tradeoffs: uses regex plus image/dynamic drawable spans or a bundled font to replace missing glyphs, or relies on EmojiCompat which replaces tofu but EmojiCompat init takes ~150ms and downloadable Noto fonts persist on devices; warns that a font approach adds ~7MB and the emoji JSON dictionary is large (JSON is 1.38MB). Demonstrates BreakIterator for grapheme counting vs code point APIs, shows variation selector-16 issues, and links a working family-emoji web builder.
