Hello,
I'm not so sure what is going on, unicode version of driver should
provide internal conversion to UTF-8, but value in log file doesn't look
as a valid UTF-8 string:
-!-"-#-$-%-&-''-(-)-*-+-,---.-/-0-1-2-3-4-5-6-7-8-9-:-;-<-=->-?-@-A-B-C-D-E-F-G-H-I-J-K-L-M-N-O-P-Q-R-S-T-U-V-W-X-Y-Z-[-\\-]-^-_-`-a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z-{-|-}-~--Р‚-Рѓ-‚-С“-„-…-вЂ

It looks like you are passing wide string as the first parameter. You
can post here your code, where you prepare this string before placing it
into the inbound buffer. More simple way to confirm this version -
replace SQL_C_CHAR with SQL_C_WCHAR in SQLBindParameters.
And of course you can try other PostgreSQL ODBC drivers, for example:
