Yes, that's my opinion now.
I did an additional test. Using Micro$oft Query with an ODBC datasource to
the SQL server I only got the correct chars if I set the option "Convert
OEM to ANSI characters".
So a good gess is that the chars are stored in some win or ms-dos codepage
(maybe cp850 or cp437) and I must make sybperl do the conversion to
iso-8859-1. Is there any way to make sybperl do this automagiclly ?
Well, it won't be difficult to do it by hand anyway, I just have to make a
conversion table between the two sets. Thanks God both are 8 bits.

No localization. The server language is English (United States), the
"default language" parameter is zero.

Nope, I never touched the stuff... 8-)
The only cfg I did in that field was the keyboard mapping.

Yup, but I whouldn't use DBlib even if I could.

I'm sure the conversion is being done by the ODBC driver. I just have to
find what's the native codepage.
Ok, thanks for your help, I'll sumarize latter.
