Character encoding: UTF-8

Character encoding is a major issue in computer systems, as different languages need a huge amount of different characters, see the amusing blog of Joel Spolsky:

The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode …

More about encoding can be found in Wikipedia:UTF-8. UTF-8 encoding tables can be found within the wikipedia article and a comparison with the first 256 characters of unicode is provided at UTF-8 char table.

For short, Exudyn uses UTF-8 character encoding in texts / strings drawn in OpenGL renderer window. However, the set of available UTF-8 characters in Exudyn is restricted to a very small set of characters (as compared to available characters in UTF-8).

Greek characters include: \(\alpha, \beta, \gamma, \delta, \varepsilon, \zeta, \eta, \theta, \kappa, \lambda, \nu, \xi, \pi, \rho, \sigma, \varphi, \Delta, \Pi, \Sigma, {\mathbf{O}}ega\).
