Also, modifying the C implementation is probably infeasible, but a Unicode version of Jcon might be possible. We no longer advertise the compiler or produce binaries for it. It is still part of the source code distribution, and we have not deliberately broken it, but we no longer support it and we cannot offer help if problems arise. The Icon Project is a name used by the group that distributes and supports the Icon programming language. A non-commercial organization, the project derives support from the University of Arizona, revenue from book sales, and user contributions.
New material is added when it's available.
Established implementations usually are updated only when there's a new version. This typically is every year or two. The Icon program library is updated on a similar schedule. Icon is the latest in a series of high-level programming languages designed to facilitate programming tasks involving strings and structures. Subsequent languages were developed at the University of Arizona with support from the National Science Foundation.
