How can I escape special symbols in scala string at runtime?

Question

Is there a general Scala utility method that converts a string to a string literal? The simple lambda function "\"" + _ + "\"" only works for strings without any special characters.

For example, the string \" (length 2) should be converted to the string "\\\"" (length 6).

Answer 1

Have a look at Apache Common's StringEscapeUtils class (docs here). escapeJava should get the job done.

Have a look at this example to see it in action (in Java).
