This is the original (1995!) technical information for both using hyptertext for language and text study, and putting it on the web. You may also review a general theory overview prepared for a non-specialist grant committee. The best learning comes by experiment, and asking around- try me:atman@vedavid.org
In general, it is easy enough to represent languages using non-Roman characters in a word processor. Plenty of fonts exist for most computers which include actual scripts of nearly every studied language. The trick is to use them on the internet which, largely, is devoted to standard Roman alphabet characters. Special web-browsers can be found, e-mail packages, and so forth. As yet, there is no standard for multiple scripts on the net. Accordingly, HTML can only be used on one-s own system, or done in a roundabout way for the net. Fortunately, this is due to change soon, at least for Mac users.
