The `chr()` function converts each given numeric value into a character
and returns the resulting string, e.g. passing 97, 98 and 99 will yield
the string `abc`.
Negative numeric values and values which cannot be converted to integers
are treated as `0`, values larger than `255` are capped to `255`.
The resulting string will have the same length as the amount of arguments
passed to the `chr()` function.
-- Testcase --
{%
printf("%.J\n", [
chr(),
chr(97, 98, 99),
chr(-1, false, null, [], {}, "0x41", 66.5, 1000)
]);
%}
-- End --
-- Expect stdout --
[
"",
"abc",
"\u0000\u0000\u0000\u0000\u0000ABÿ"
]
-- End --
