Or the verbose way:
"abc\\ndef\\tghi"
But if the string is only known at runtime, you'd probably have to use
std.regex.replaceAll or something like that to manually escape
characters. Or implement manual substitution with a pipeline:
string myString = ...;
string escapedStr = myString
.chunks(1)
.map!(c => (c == "\n") ? "\\n" :
(c == "\r") ? "\\r" :
(c == "\t") ? "\\t" :
c)
.joiner
.array;
