I finally got around to refreshing this article, by converting the Bengali, Malayalam and Oriya examples to Unicode text. Back when I first wrote the article, it was hard to find fonts for those scripts.
I also added a new feature: In the HTML version, click on any of the examples in indic text and a pop-up appears at the bottom right of the page, showing which characters the example is composed of. The pop-up lists the characters in order, with Unicode names, and shows the characters themselves as graphics.
I have not yet updated this article’s incarnation as Unicode Technical Note #10. The Indian Government also used this article, and made a number of small changes. I have yet to incorporate those, too.
