Language design: Escaping escapes
Most languages use special characters or special sequence of characters to denote the use of special directives. For instance, in C format strings:
"\n" denotes new line, and if you wanted to have backquote n, you'd have to write "\\n".
In VB, since " is used to delimit strings, you'd use "" to mean double quotes. eg. "He said ""Boo""!"
In each case, if you wanted to show source code in the same language, it gets very painful, since you'd have to escape escapes. For instance to show the example of <img> tag in HTML, I'd have to do this:
<img src="example" >
In C you'd do this:
printf("For example: printf(\"Hello World\\n\"); prints \Hello World\"\n");
Are there any languages or patterns which handle this kind of situation more elegantly?
