Renaming feature for Account object is not working with special character "%".

Issue: Special character “%” issue in record renaming.
Resolution:
1. Due to Technical reasons ,” %” does not support in the folder path and According to the Salesforce Security reason , all the API requests going outside should be URL encoded.
2. “%” is one of the special characters which is replacing all other special characters during UTF Encode.
3. So, For “%” , we need to use a substitute in the formula field
