I'm adjusting a few things so that all builders are tagged correctly and the new slave also ends up in the base image.

That is to say: more or less. This fully displays multi-line command line arguments, so some progress has been made. Unfortunately, this isn't the solution yet, as it leads to the same problem as with Stax: each line is treated as a separate argument. I believe executing an empty source file should also fully display the first command line argument. That would solve the problem.
This also works the same way for single-line string input. However, it breaks the sample code because the action under "Accessing arguments" constantly displays the triple quotes. I don't know the language well enough yet, and I wouldn't know how to repeat `I,I,I,I,I,I,I,` the required number of times. I've tried a few things, but it's making me far too nervous at the moment. With something similar to what it does for numeric values, absolutely nothing seems to work. So far, changes in `play.go` have also failed every time, so I'm leaving it as is for now.

Command-line arguments containing Unicode characters are not yet supported. Almost.

["In mathematics and computing, the hexadecimal (also base 16 or simply hex)
numeral system is a positional numeral system that represents numbers using a
radix (base) of 16. Unlike the decimal system representing numbers using 10
symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"-"9"
to represent values 0 to 9, and "A"-"F" (or alternatively "a"-"f") to represent
values from 10 to 15.
Software developers and system designers widely use hexadecimal numbers because
they provide a human-friendly representation of binary-coded values. Each
hexadecimal digit represents four bits (binary digits), also known as a nibble
(or nybble). For example, an 8-bit byte can have values ranging from 00000000 to
11111111 in binary form, which can be conveniently represented as 00 to FF in
hexadecimal.", "Code Golf", " !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~", "Lorem ipsum dolor sit amet,
consectetur adipiscing elit
