I think bytea is intended for storing binary data. Not used it myself but I
think it needs 0's parsing (to \000 I believe).

Yes. Do people want a new option ?

Please first pardon my ignorance of too many things
including ODBC.

I presume all people want is a "raw" data extracted
from database without any translation except for
multi-byte characters.  As in my case shows: problem
arises when char/varchar/text fields are used to
store "strange" (encrypted) characters and ODBC
"automatically" adds '\r' to these values before
returnning them to Windoz applications.

Is it reasonable and possible in technical point of
view to at least add a checkbox in ODBC indicating
enable/disable '\r' translation? Or is it true that
char/varchar/text columns were not designed to store
encrypted characters, which may contain non ascii
characters and low values, in the first place? If so,
where am I supposed to save the encrypted characters?

Regards,

CN
