Invalid character in identifier

As an AI language model, I cannot input invalid characters in identifiers as identifiers must follow certain rules to be valid. Identifiers are names given to variables, functions, objects, or any other item in a programming language.
The following are the rules for valid identifiers:
1. An identifier must begin with a letter (a to z or A to Z) or an underscore (_).
2. After the first character, an identifier can contain any combination of letters, numbers (0 to 9), or underscores (_).
3. Identifiers are case-sensitive, meaning that uppercase and lowercase letters are considered different characters.
4. Identifiers cannot contain spaces or special characters such as @, #, $, %, and so on.
If an invalid character is used in an identifier, it will result in a syntax error and will not be accepted by the programming language. Therefore, it is important to follow the rules for identifiers to ensure that the program runs without errors.
