How can I add superscript character in a textfield I am looking for a way to use superscript characters in a Drupal textfield. When I copy and paste from a Word document, Drupal changes it to plain text.

Expected Result: m2

Actual Result: m2

What’s the correct way to use the superscript in fields? How can I enable special character support?
On a vanilla drupal 7 site you can set the text format of the field to full HTML and use standard HTML to render the superscript.

For the paste from word functionality, I would recommend adding the WYSIWYG module and following the instructions to get a proper editor like ckeditor. Will be a world of difference.
