Not in all cases. But this particular Ister interpreter is designed
to run CGI scripts. When it comes to CGI languages, I have the philosophy
of graceful degradation: If I can interpret it, I will. Otherwise,
the user (the person who is browsing, not the webmster) might be confused.

If it follows no standards, my interpreter will throw up hands. But if
the source code says it is in UTF-8, and I can decode it, I will. If it
says it is in Latin1 (or some other encoding), I will convert it to UTF-8.
In either case, my output will always be legal UTF-8.

Well, the worst bug this particular language will produce is HTML with
the wrong text or tags. Presumably, any webmaster worth his keep will check
the output of his code before posting it on the web, and will fix his
All it does is convert from one mark-up language (Ister) to another (HTML/
SGML/XML), e.g., it will convert;
^p (Hello, World!^/br ^b (Here I come!))
<p>Hello, World!<br /><b>Here I come!</b></p>
No big security issues at stake here. :)
