The new exciting thing are special characters in plots, comments and output. Here is a somewhat random example.
To get this, you need to define Unicode strings in Euler. E.g., the title of this plot is labelled
>title = u"α³ - α"
You can use very many HTML codes, so-called „entities“. You can also use Unicode numbers. You can use the entities in comments too. This is a bit faster and more friendly than a line of Latex code.
In EMT, Unicode strings are just strings with a special flag. They draw via the Unicode API of Windows. This works for simple line output too.
>sa = u"α"; >sa + " = " + 45 + u"°" α = 45°
Internally, the interpreter and most of the surface still runs in plain ASCII. But some strings are translated to Unicode.
Thanks to Evgeniy who pushed me into doing this!
