fn compile_gbk_function( &self, entity: &EntityDescriptor, args: &[Expr], params: &mut Vec<Value>, ) -> Result<String, SqlCompileError>

Compile a GBK sort expression. The default implementation returns an error because GBK encoding conversion is dialect-specific. PostgreSQL dialects should override this to use convert_to(arg, 'GBK').
