A possible idea would be: ONLY_SKIP_FIRST_INVALID_CHAR

This would allow to skip only non-ASCII characters in 8-bits
encoding. For example a two bytes sequence may be encoded in a legacy
8-bit encoding, where the first byte encodes for an invalid ASCII
character, and the second for an ASCII character, but which results in
an invalid UTF-8 two bytes sequence (example: E622).

On the other hand this use case seems too much specific.
