When I put INSTRING("√7","√") directly into CAS, it returns 1 as expected.

However when I put the exact same thing into programs, it returns 0. CAS or non-CAS, it doesn't matter.
Code:
EXPORT norm_instring_bug(expression)
BEGIN
  return instring(string(expression),"√");
END;

#cas
cas_instring_bug(expression):=
BEGIN
  return instring(string(expression),"√");
END;
#end

It might have something to do with Prime auto-adding spaces, which I found to have caused some issues during my testing. For example, Prime changes "√" to " √ ". If we now calculate INSTRING("√7"," √ "), it returns 0.

When I put in the following:
Code:
EXPORT norm_instring_bug(expression)
BEGIN
  RETURN INSTRING(STRING(expression),"√");
END;

I get 2 in RPN mode when I enter "√7". I tried with all capitals as well as lowercase keywords. I get 2 every time.
