Remove emoji from text

Strip every emoji out of a caption, a filename or a dataset. Emoji are removed as whole characters, so a skin-tone modifier, a flag or a multi-part sequence like 👩‍💻 goes in one piece — the naive approach removes the visible part and leaves invisible joiners and modifiers scattered through your text, which then break string comparisons elsewhere. Tidying the leftover spacing is optional, so your original layout survives unless you ask otherwise.
