My standard encoding is UTF-8 on all levels so I don't need this
high-cost call:
plpy.execute("select setting from pg_settings where name =
'server_encoding'");
Additionally I want to get the original cases.
For this purpose my solution is still fitting to my need. But it is not
the one you have cited below, but:
CREATE OR REPLACE FUNCTION simplify (str text)
RETURNS text
AS $$
import unicodedata
s = unicodedata.normalize('NFKD', str.decode('UTF-8'))
s = ''.join(c for c in s if unicodedata.combining(c) == 0)
return s.encode('UTF-8')
$$ LANGUAGE plpythonu;
Andi
2) Transfering this to PL/Python:
CREATE OR REPLACE FUNCTION test (str text)
RETURNS text
AS $$
import unicodedata
return unicodedata.normalize('NFKD', str.decode('UTF-8'))
$$ LANGUAGE plpythonu;
