Steps to reproduce the behavior:
Train a Text Classifier using this dataset: https://www.kaggle.com/uciml/sms-spam-collection-dataset

Riproducete il malfunzionamento con il dataset Kaggle collegato sugli SMS spam, quindi iniziate dalla riga 112 di AutoMLService/AutoMLEngineService/AutoMLEngine.cs e seguite la chiamata di inferenza delle colonne fino al percorso InferColumns di ML.NET. Verificate che i caratteri di ritorno a capo e di nuova riga nel dataset non causino più errori di colonne incoerenti e che l’addestramento del classificatore di testo venga completato.

Scritto dal modello di indicizzazione a partire dal testo della issue.
