invalid-character-backspace / E2510

Message emitted:

Invalid unescaped character backspace, use "\b" instead.

Description:

Moves the cursor back, so the character after it will overwrite the character before.

STRING = "Invalid character backspace "  # [invalid-character-backspace]

Correct code:

STRING = "Valid character backspace \b"
