Programming With the Text Encoding Conversion ManagerA fallback mapping is a sequence of one or more coded characters in the destination encoding that is not exactly equivalent to a character in the source encoding but which preserves some of the information of the original. For example, (C) is a possible fallback mapping for ©. In general, fallback mappings are used as a last resort in converting text between encodings because they are not reversible and therefore do not lend themselves to round-trip fidelity conversions.
