Problem 1.Intelligent Form Extractor or Form Extractor both are not recognizing superscripts in document understanding Framework.
for ex:- is recognised as B2
Can you please let me know how can we get text with superscripts intact
Problem 2.Intelligent Form Extractor is not keeping case of letters intact for a particular field in my document . The data is changed to lowercase.I want to retain the text cases as in the pdf.Regex and Form Extractor are not able to extract the data

Can someone help me to resolve both these problems please ?
