Unicode barcodes

For some reason I decided to see if Code 39 barcodes were renderable with Unicode block drawing characters. The answer is yes. This should be scannable if it is all on a single line:

│ │█ █│││█ █ │█││█ │█ █││ │█ █││ │█ ││█│││█│ █ █│█ ││││█ █ ││ │█ █│

Datamatrix

This one doesn't seem to work, possibly due to spacing..
