The string passed to ‘display’ above is pure ASCII so I wonder how we
can get that exception, apart from having ‘current-error-port’ using a
non-ASCII-compatible encoding such as UTF-32.

Hi,

> `("put-char" "conversion to port encoding failed" 84 #<output: file 2>
> #\2)'.

Could the error be due to the 7-bit encoding in HTTP headers? [1] The
"84" is EILSEQ from errno.h. [2] Wingo added the functionality here. [3]

I also submitted a patch to resolve in the errno in Guile. [4]

Kind regards
Felix
