Encoding logic for MS Access "General" (Access 2010+) text index entries.

Extends GeneralLegacyIndexCodes with updated character tables for Unicode code points that were assigned or reweighted in the Access 2010 release. The byte-format structure (inline bytes, extra bytes, unprintable bytes, crazy codes) is identical to the legacy variant; only the per-character code tables differ.

Character handlers are loaded lazily from:

private static GeneralLegacyIndexCodes.CharHandler getSurrogateCharHandler(char c)

Returns the handler for the given surrogate char. The third run of the high surrogates has no weight in the table, so those are ignored.
