Some characters are being replaced with underscore character "_" when migrating notes document to Sharepoint Document Library

This is due to the some characters are invalid character in the SharePoint Document Library.
 

Notes Migrator for SharePoint will replace those invalid character with an underscore character "_"
These are the following invalid character in SharePoint Document Library: ~ " # % & * : < > ? / \ { | }.

When try to update the document library with invalid character in Sharepoint itself, it is getting the following error:
The file or folder name "Test " & ampersand" contains invalid characters. Please use a different name. Valid file or folder names cannot begin or end with a dot, cannot contain consecutive dots and cannot contain any of the following characters: ~ " # % & * : < > ? / \ { | }.
