I want to get the second character from comment-start.
Would one use (aref kmnt 1) ?
(let* ( (kmnt (string-trim comment-start))
(lngt (length kmnt)
(ankr (if (= lngt 2)
(aref kmnt 1)
kmnt)) )

Any reason not to do (aref ... 1)? Not sure what you're worried
about.

What is the standard way of capturing characters from strings, is it with aref ?

I don't know what makes something "standard" for you. As covered
in (info "(elisp) String Basics") a string is an array, and as
covered in (info "(elisp) Array Functions"), aref can be used to
fetch an element of an array.
And as a random sample of some core code, aref is used 17 times in
files.el from what I can see.
Cheers,
