mariadb-connector-odbc-master - Error missing character

Hi Team,

we are newly migrating the maria DB (10.5.13) and to compile some of c to dll file, we are using Visual studio 2015 for compilation and copied the following files from 2 different location,

mariadb-connector-odbc-master : for ma_odbc.h File and supporting files.
MariaDB ODBC Driver 64-bit : for maodbc.lib file

Both patched under our code and tried to run the build. getting following errors.
