Sorry for the delay. We had very strong production constraint, and I had to let it go
for a while.
Well, How can i know about the internal coding of this letter in the database ?
The texts where inserted from command line inserts. When inserted from JDBC (so it's
supposed to be unicode),
I can't see any difference, even in the generated dump file.
Today I've seen a post about the same problem, that gives a solution to produce a
working dump: pg_dump -d $dumpfile.
This command produce this kind of lines (you :
INSERT INTO "element_texte" VALUES (634,'','Filtration du Plasma','\350');
I noticed that using \xxx notation i can handle special characters in queries from
psql command line, too.
But it doesn't look like unicode coding (cf www.unicode.org/charts and
LATIN1-Supplement), as I was expecting.
So, I have the following questions:
- What kind of code is this ?
- can I get the translation chart somewhere ?
- why isn't it UNICODE ?
- why do I have to use \xxx code (and not 0x..., or directly the special character
like "é") from the psql command line,
although it is supposed to support UNICODE ?
- why don't we find this kind of characters in the dump file when the -d option is
not set ?
(I assume this cause the restore to fail, and I think it could be considered
as a bug).
Thank you for your help
