--- Takes a table containing an arbitrary number of integers in the range 0..255 and converts it 
--- into a binary stream of the corresponding binary chars.

--- @param charIndices a table containing 0...N arguments; each in the range 0..255
---
--- @return a string containing binary content, one byte for each input integer.
-function pgfplotsGetLuaBinaryStringFromCharIndices(charIndices)
-	-- unpack extracts only the indices (we can't provide a table to string.char).
-	-- note that pdf.immediateobj has been designed to avoid sanity checking for invalid UTF strings -
-	-- in other words: it accepts binary strings.
-	--
-	-- unfortunately, this here fails for huge input tables:
-	--   pgfplotsretval=string.char(unpack(charIndices));
-	-- we have to create it incrementally using chunks:
-	local len = #charIndices;
-	local chunkSize = pgfplotsGetLuaBinaryStringFromCharIndicesChunkSize;
-	local buf = {};
-	-- ok, append all full chunks of chunkSize first:
-	local numFullChunks = math.floor(len/chunkSize);
-	for i = 0, numFullChunks-1, 1 do
-		table.insert(buf, string.char(unpack(charIndices, 1+i*chunkSize, (i+1)*chunkSize)));
-	end
-	-- append the rest:
-	table.insert(buf, string.char(unpack(charIndices, 1+numFullChunks*chunkSize)));
-	return table.concat(buf);
