That’s mainly with gcc on GNU/Linux with a UTF-8 locale or with PHP with 
a <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 
in the XHTML document.

What do you call “manual inserting”?

That’s a very special case and a few \ are not a big problem.
You could use existing characters as “string litteral quotes”. I’ve 
never used APL so I don’t remember the meanings of its symbols, but 
couldn’t ⍘ U+2358 APL FUNCTIONAL SYMBOL QUOTE UNDERBAR or ⍞ U+235E APL 
FUNCTIONAL SYMBOL QUOTE QUAD work as “string litteral quotes” in a new 
programming language?

Hard to input? Not harder than the new symbols you’d like to propose. 
That’s only a matter of keyboard layout and input method.

In what would they be easier to input?

If the IDE inputs your new character when you press tab, then your new 
character is a tab…
