This seems the same as "Unicode" and the technique is interesting. A while back I had to use unicode to create a simple filled box in a tcl/tk window. It had a red foreground to look like an LED indicator. The 4 red boxes had a glyph representation ; \u2588\u2588\u2588\u2588 It took quite a while to go through thousands of glyphs, just to find what used to be (IIRC) extended ASCII. I would be interested in the actual programs doing this conversion. I think the tcl interpreter script uses the "\u" to flag the unicode example above. Been a while. Surprised I found this old stuff.
