UCKeyOutput & related stuff
The interpretation of UCKeyOutput depends on bits 15-14.
If they are 01, then bits 0-13 are an index in UCKeyStateRecordsIndex (resource-wide list).
If they are 10, then bits 0-13 are an index in UCKeySequenceDataIndex (resource-wide list),
or if UCKeySequenceDataIndex is not present or the index is beyond the end of the list,
then bits 0-15 are a single Unicode character.
Otherwise, bits 0-15 are a single Unicode character; a value of 0xFFFE-0xFFFF means no character
output.
UCKeyCharSeq is similar, but does not support indices in UCKeyStateRecordsIndex. For bits 15-14:
If they are 10, then bits 0-13 are an index in UCKeySequenceDataIndex (resource-wide list),
or if UCKeySequenceDataIndex is not present or the index is beyond the end of the list,
then bits 0-15 are a single Unicode character.
Otherwise, bits 0-15 are a single Unicode character; a value of 0xFFFE-0xFFFF means no character
output.

UCKeyStateRecord & related stuff

charData and set the state to nextState. Otherwise, output the state terminator from
UCKeyStateTerminators for the current state (or nothing if there is no UCKeyStateTerminators
table or it has no entry for the current state), then output stateZeroCharData and set the
state to stateZeroNextState.

first entry in keyboardTypeHeadList is the default entry, which will be used if the
keyboardType passed to UCKeyTranslate does not match any other entry - i.e. does not fall
within the range keyboardTypeFirst..keyboardTypeLast for some entry. The first entry
should have keyboardTypeFirst = keyboardTypeLast = 0.
