Crash on parsing sql query with Cyrillic letters

Hello,

I'm using DataFusion to query data from my csv file. The file contains columns with Cyrillic letters and when I write query like this one, I get a crash.

Code sample:
{code}
let mut ctx = ExecutionContext::new();
let csv_file = CsvFile::try_new(args.input.as_path().to_str().unwrap(), CsvReadOptions::new())?;
ctx.register_table("transactions", Arc::new(csv_file));
let df = ctx.sql("SELECT "ДАТА" FROM transactions")?;
let results = df.collect().await?;
log::info!("result: {:?}", results);
{code}
