Line 273:
The terminal might support UTF-8, but its fonts might not have every Unicode character. Unless they have U+25B3, the output will not look correct. Greek letters like U+25B3 tend to be common, but some fonts might not have Chinese characters (for example), and almost no fonts have dead scripts such as Cuneiform.

This code works for Unix/Linux, Windows XP cmd terminals don't support UTF-8.
<lang zkl>if(System.isUnix and T("LC_CTYPE","LC_LANG","LANG").apply(System.getenv)
.filter().filter("holds","UTF"))
println("This terminal supports UTF-8 (\U25B3;)");
else println("I have doubts about UTF-8 on this terminal.");</lang>
