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? > How can you search and replace for these?

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. -- Michael Fuhr ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
