I'd need a little more information on the context in which you planned to make use of the characters -- for example, did you want to display them in an X application? Have them appear in a technical paper? Be able to enter them on a keyboard (for a rather advanced calculator)? Make them appear on a Web page? The second of the above is where I've had occasion to use them (with the first as a bit of a special case), and for that, I would use groff (& friends, especially eqn). Others, especially mathematicians (from what my brother tells me), tend to use TEX (which is nice, but I really like pipes). Once you've got source in some markup language (such as that used by TEX or groff), it can be transformed into someting that has the requisite appearance; for example, groff generates PostScript (by default), which can be dumped to a garden-variety PostScript printer, or viewed on an X server via ghostscript, for example. david -- David Wolfskill UNIX System Administrator dhw@whistle.com voice: (650) 577-7158 pager: (650) 371-4621 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
