Invalid identifier ' '. Apex identifiers must start with an ASCII letter

Hi Sumit,

Greetings!

Can you please try by changing the code on the lines where you get the error and please be informed that it could not be the issue with the "Identifiers" but using them in the incorrect way.

Reference:https://developer.salesforce.com/forums/?id=9060G000000MV8PQAW

Kindly mark it as best answer if it helps so that it can help others in the future.

Warm Regards,
