SQLite is not particular about the text it receives and is more than

well-formed UTF-8 or UTF-16.  Thus, programmers who want to store
IS08859 data can do so using the UTF-8 interfaces.  As long as no
attempts are made to use a UTF-16 collating sequence or SQL function,
the byte sequence of the text will not be modified in any way.
