How can I make gambit to print a Unicode character's symbol (or glyph)?
For example, I want to display the Unicode infinity symbol ∞ (#\u221E).
Calling `(display #\u221E)` or `(print #\u221E)` throws the REPL into an infinite loop.
(This happens for most Unicode literals I tried, not just the infinity symbol :-))

       $ gsc
       Gambit v4.8.4

> (print #\u221E)
*** ERROR IN ##wr-ch -- Can't convert to C char-string
(write-char #\*** ERROR IN ##wr-ch -- Can't convert to C char-string
(write-char #\*** ERROR IN ##wr-ch -- Can't convert to C char-string
(write-char #\*** ERROR IN ##wr-ch -- Can't convert to C char-string
(write-char #\*** ERROR IN ##wr-ch -- Can't convert to C char-string
