[mapserver-users] encoding problem when using variable runtime substitution

[Steve.Toutant at inspq.qc.ca]

Hi,
I have a layer which connect to my postgis DB with client encoding 
win1252. 
CONNECTIONTYPE postgis
CONNECTION "host=serveurpg dbname=geo user=xxxpassword=xxx port=5432 
options='-c client_encoding=WIN1252'"

That use to work for years, just before I start using variable 
substitution.

My problem is when using runtime substitution in a FILTER
ex.: FILTER (periode = '%periode%' )

If I send a wms getmap request with the wms parameter periode = '2001 à 
2003'

It seems that mapserver receive '2001 à 2003' encoded in utf-8, and tells 
postgis that it is in win1252, so nothing is returned.

If I use CONNECTION "host=serveurpg dbname=geo user=xxxpassword=xxx 
port=5432 options='-c client_encoding=utf-8'"
it works, but I don't want to do that because I'll have a lot of code and 
mapfiles to change.

Is there a reason why mapserver would think a string is encoded in utf-8?
Maybe I'm totally on a wrong track, if so any idea where could be the 
problem?

Thanks
steve
