What do you mean by "high value unicode characters (Unicode 0x2)"?
Characters with code points in a plane other than Plane 0 (BMP,
Basic Multilingual Plane), i.e., with a code point greater than
U+FFFF?

If I understand what you're asking then you should be able to use
regexp_replace (8.1 and later) to fix the data. Example:

UPDATE tablename
SET columnname = regexp_replace(columnname, E'[\\U00010000-\\U0010FFFF]+', '', 'g')
WHERE columnname ~ E'[\\U00010000-\\U0010FFFF]';

If that doesn't help then please clarify the problem.
