Hi,

You can change calcite default encoding via custom java option in dremio-env configuration file.  
Here is example how set encoding to UTF-16:  
DREMIO\_JAVA\_SERVER\_EXTRA\_OPTS=’-Dsaffron.default.charset=UTF-16LE -Dsaffron.default.nationalcharset=UTF-16LE -Dsaffron.default.collation.name=UTF-16LE$en\_US’
