Implementation

@useResult
String removeMatchingWrappingBrackets() {
  if (!isBracketWrapped()) return this;
  // Slice by grapheme count, not code-unit `length`: `substringSafe` is
  // grapheme-indexed, so a code-unit length over astral content removed the
  // wrong span (e.g. '(😀)' kept the trailing bracket).
  final int graphemeCount = characters.length;
  return substringSafe(1, graphemeCount - 1);
