Since I had a few minutes tonight, I created a quick hack in Python.
It should be attached to this message, unless the list server removes it.

Here is a sample usage in psql:

dwn=# \i ./check_code_page.sql
CREATE FUNCTION
dwn=# select check_code_page('abcxyz', 'cp037');
 check_code_page
- -----------------
 t
(1 row)

dwn=# select check_code_page('abcä', 'cp037');
 check_code_page
- -----------------
 f
(1 row)

You'll note that the a-umlaut character fails in the conversion to
cp037 (U.S. EBCDIC).
