Hi Tilmann!
encoding in psql gives me SQL_ASCII for encoding. I followed all
threads on encoding at openacs.org but nothing worked for me, so I
tried it myself.
Now I have no problems with strings that are sent via post or get
operations or retrieved from the database.
But I've also put this in my server.tcl file:
set charset iso-8859-1
ns_section "ns/parameters"
ns_param URLCharset $charset
ns_param OutputCharset $charset
ns_param HackContentType true
But only after the modifications of ReturnHeaders and
ReturnHeadersNoCache the whole thing worked and I've had no problems
so far. I've tested it heavily using german umlauts.
