You already got advice, but anyway: what this means is that the string
cannot be converted to the current locale.

In Guile 1.8, strings were just byte sequences, like in C.  In 2.0,
strings are sequences of Unicode codepoints, which means that they must
be encoded when written to an output port.

HTH,

PS: Nitpicking: I guess it should be “GNU Denemo” (as in “the Denemo
    package of GNU”), rather than “GNU/Denemo” (“GNU over the Denemo
    kernel”?)  :-)
