Thread: pgtcl and umlaut
Hello, I'm using postgresql 7.0.2 on a PC running Linux (Mandrake 7.2). I'm developing a application using the Tcl/Tk binding pgtcl (included in the postgresql distribution). I have problems with the german umlaut (ÄÖÜ): it is possible to insert and read strings containing umlaut letters in a pgtcl application, but when the database sorts the table, the sort order is wrong: A Ä Ö Ü B C ... instead of A Ä B C ... O Ö P ... U Ü V ... The database dump with otion -d (proper insert strings) prints \303\204 for Ä \303\226 for Ö \303\234 for Ü I tried differend encodings in the database (UNICODE, LATIN1, SQL_ASCII) as well as in tcl (unicode, iso8859-1) but there was no impact on the sort result. You find a pgtcl script attached to this mail that demonstrates the problem. Before starting the script you have to create a database: createdb -E UNICODE sort_umlaut then you have to run the script (pgtclsh must be installed in /usr/bin, otherwise edit the first line of the script): chmod u+x problem.tcl ./problem.tcl The script prints the sorted table. Afterwards you can print the contents of the database: pg_dump -d sort_umlaut Maybe somebody has a solution for the problem ;-) Thanks in advance, Gerd -- Gerd Scheidhauer http://www.gerdscheidhauer.de phone:+49 721 722 34 16
I'm not sure what version of Tcl are you using, but I guess it's a general problem of Tcl >= 8.1. The only solution I could imagine so far is down grading Tcl to 8.0. -- Tatsuo Ishii > I'm using postgresql 7.0.2 on a PC running Linux (Mandrake 7.2).

I've forgotten the details of this problem, but I do remember that the
newer Tcl versions want Unicode (UTF-8) representation. Would it work
to build Postgres with MULTIBYTE support and set client encoding to
UTF-8?

But he is using 7.0, and he needs to upgrade to 7.1 to have UTF-8 <--> LATIN1 conversion. -- Tatsuo Ishii
