ImageFont.load_default() has no emoji glyphs, and PIL/FreeType don't skip an unsupported codepoint -- they substitute a visible ".notdef" tofu box, which read as a rendering glitch rather than "not supported." Stripped instead (covers the standard emoji Unicode blocks, skin-tone modifiers, and the ZWJ used to combine them into one glyph), with surrounding whitespace collapsed.
