impl<I: Iterator<Item = char>> Iterator for Replacements<I> type Item = char;A transformation which replaces CJK Compatibility Ideograph codepoints with normal forms using Standardized Variation Sequences. This is not part of the canonical or compatibility decomposition algorithms, but performing it before those algorithms produces normalized output which better preserves the intent of the original text.
Note that many systems today ignore variation selectors, so these may not immediately help text display as intended, but they at least preserve the information in a standardized form, giving implementations the option to recognize them.
