hello

i would like to search a table column for a range of non-ascii
characters, or a particular non-ascii character. how can i do this?

the column can be any string like "hello, world" or "norwegian
characters æøå here".

refer to these pseudo examples:

SELECT * FROM TABLE WHERE COLUMN CONTAINS CHARACTERS BETWEEN 128 and 255;

SELECT * FROM TABLE WHERE COLUMN CONTAINS CHARACTER = 240;

thanks
