The intent, of course, is to offset the raw string literals non-translation of 
Unicode escapes and escape sequences. That is, have the multi-line cake and eat 
the escapes too.

So a developer could have

        String s = `
                   \t\tTitle
                   \t\t\tbody
                   ...

                   `.align().escape();

to have tabs inserted in the string.

"\\" "\u005c\u005c" and `\` all translate to the same string. `\u005c` 
translates to "\\u005cā€. `\u005c`.unescape() thustranslates to be the same as 
"\\ā€, "\u005c\u005c" and `\`.
