Great, thanks! (I wanted to create a proper table at some point, but
didn't take time to think about how to create an arbitrary number of
columns.)

But then I have another question: how can I use \HL and \VL? The
following code doesn't create any line at all:

function draw_table(unicode_start,n_columns)
	context.bgroup()
	context.definedfont { "Serif at 20pt" }
	context.starttable { string.format("*{%s}{|w(1.2em)}|", n_columns) }

	for i=0,0xF do
		context.VL()

		for j=0,n_columns-1 do
			context(unicode.utf8.char(unicode_start+i+16*j))
			context.VL()
		end
		context.NR()
		context.HL()
	end
	context.stoptable()
	context.egroup()
end

PS: I still don't know the reason why my example fails, but I will
ignore that for a moment since this does the job as well.
