Unescaped multiline strings are deprecated since version 3.4.0 and should not be used anymore.

## Noncompliant Code Example

    @error "blabla...
            blabla...
            blabla...";

## Compliant Solution

Add `\` at the end of each line to escape the multiline string. Also add `\a` to add a carriage return.

    @error "blabla...\a\
            blabla...\a\
            blabla...";
