-- Creation 1: a string can be created from an integer value by a conversion

+- Creation 1: a string can be created from an integer value by a conversion;
+ the result is a string containing the UTF-8 encoding of that code point.
+ string('x') yields "x"; string(0x1234) yields the equivalent of "\u1234"
- Creation 2: a string can by created from an array of integer values (maybe
just array of bytes) by a conversion
a [3]byte; a[0] = 'a'; a[1] = 'b'; a[2] = 'c'; string(a) == "abc";
