Lexical Error (LEX0012): String literal contains Invalid escape characters.

In STRING literals, escape sequences can be used to enter particular characters, such as ' (quot), or control codes. In your project, the parser detected an invalid combination of the escape character with other characters.

Examples:

'$R$N' is valid

'$'' is valid and the only possibility to use the ' (quot) character in a string

'$0D$0A' is valid. Characters/control codes are specified as hex code

'$M' is invalid because M is not a control code.

'$R$N'	is valid
'$''	is valid and the only possibility to use the ' (quot) character in a string
'$0D$0A'	is valid. Characters/control codes are specified as hex code
'$M'	is invalid because M is not a control code.
